Simpson will it take 112 / 17 km to drive 560 km on a perfectly straight highway.

You can replace this computation with d = rt, which stands for "distance equals rate times time." To calculate speed or rate, use the speed formula, s = d/t, which asserts that speed is equal to distance divided by time.

The difference between speed and velocity is the amount of distance an object covers in a given amount of time and in a certain direction. Speed is a scalar quantity while velocity is a vector.

We know that:

v = 85

First, let us make a sketch of the question:

From the diagram, the blue circle represents his starting position while the black circle represents his final position.

The total distance the boy covers is the sum of his two journeys, to the east and then to the west.

That is:

The boy's displacement is the distance between his starting position and his final position.

Since the west is taken as negative direction and the east taken as the positive direction, it means that 4km east means +4km and 1.5

For the moving car, if you double your driving speed;

a. the time required to come to a stop will increase by a factor of 2.

b. the distance needed to stop will increase by a factor of 2.

The formula relating to the acceleration, speed, time, and distance traveled of an object is a formula of the equations of motion.

The equations of motion are given below as follows:

v = u + at

s = ut + ¹/₂at²

v² = u² + 2as

where:

v = final speed

u = initial speed

t = time taken

The the acceleration of the sled of mass 100 Kg will be 1.5 m/s².

A drag is force that opposes the motion of an object by acting in the direction opposite to its motion. It is of two types namely - Static friction and kinetic friction. The static friction is given by - F[S] = μ[s]​ x η and the  kinetic friction is given by F[K] = μ[k] x η.

Given is a football blocking sled which has a mass of roughly 100 kg. A football player applies a force of 500 N to the sled, and there is a 350 N frictional force acting on the sled.

Assume that the force applied by the player is - F[P] = 500 N and the force of friction is - F = 350 N.

Now, for the motion of the sled with acceleration [a], we can write -

F[P] - F = ma

a = {F[P] - F}/m

Substituting the values, we get -

a = (500 - 350)/100

a = 150/100

a = 15/10

a = 1.5 m/s²

Therefore, the the acceleration of the sled of mass 100 Kg will be

Recall that the gravitational pull is given by

Where m is the mass of the astronaut, ME is the mass of Earth, r is the distance between them, and G is the gravitational constant.

The above relation states that the force of gravitation is directly proportional to the mass of two objects and is inversely proportional to the square of the distance between them.

If the astronaut weighs 200 pounds and the radius of the Earth is 4000 miles then

When the astronaut moves 4000 miles above the earth's surface then the distance between them is

4000+4000 = 8000 miles

The distance is measured from the center of the earth so the radius must be included.

So, the new force of gravitation is

Therefore, the astronaut weighs 50 pounds 4000 miles above the earth's surface.

This makes sense because as you go further away from the center of the Earth then your weight becomes less due to less force of gravity.

Sound waves are faster in water

STEP-BY-STEP EXPLANATION:

Sound travels differently in water than it does in air.

Sound waves travel faster in denser substances because neighboring particles will more easily collide with each other.

Water is denser than air, which means that sound waves travel much faster in water than in air.

Although they travel faster in water, we must keep in mind that the human ear evolved to hear sounds in the air and is not as useful when submerged in water.

The work done on the asteroid by the constant force is 4.06 × 10¹¹ joules and the force experienced by the asteroid is 1.89 × 10⁵ newtons

what is work energy theorem?

work energy theorem is an important phenomenon in physics which states that the change in kinetic energy is equal to the work done by the object.

This law is basic part of conservation of energy.

what is newtons law of motion?

Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.

given:

mass of the asteroid = 5.8 x 10⁴ kg

initial speed of the asteroid v₁ = 6800m/s

final speed of the asteroid v₂ = 5600 m/s

displacement of the asteroid = 2 × 10⁶ meters

a)

using work energy theorem for the asteroid we get,

work done = change in kinetic energy

work done = 1/2 × m × (v₂) ² - 1/2 × m × (v₁) ²

work done by the force on the asteroid is = 1/2 × 5.8 x 10⁴ (1.4 × 10⁷)

work done by the force on the asteroid is = 4.06 × 10¹¹ joules

b)

first, we will have to find the acceleration of the asteroid,

using newtons third law of motion we get,

a = 14/4

a = 3.5 m/s²

therefore, the force can be calculated using relation f = m × a

here,

m is mass

a is acceleration

therefore, the force on the asteroid is = 5.8 x 10⁴ × 3.5

the force on the asteroid is = 1.89 × 10⁵ newtons

therefore, the work done on the asteroid by the constant force is 4.06 × 10¹¹ joules and the force experienced by the asteroid is 1.89 × 10⁵ newtons

ANSWER

A. The object has a negative velocity

EXPLANATION

We want to describe the slope of a position-time graph that is negative.

If the slope of a position-time graph is negative, it implies that the velocity is also negative. In other words, as time increases, the velocity also decreases.

As velocity decreases, it implies that the acceleration also decreases.

Therefore, we have that the acceleration of the object is negative.

The answer is option A.

The magnitude of the torque that slows the turntable is equal to 2.17 × 10⁻³ N.m.

Torque can be described as the measure of the force that can cause the rotation of an object about an axis. The force causes an object to accelerate similarly, torque causes an angular acceleration. Therefore, torque is the rotational equivalent of linear force.

Given, the rotational speed of the turntable, ω = 78 rpm = 8.16 rad/s

The time turntable takes to stop, t = 45 s

The rotational inertia of the turntable, I = 1.2 × 10⁻² Kg.m²

From the rotational kinetics equation, the angular acceleration:

[tex]\omega_f = \omega +\alpha t[/tex]

The final speed of the turntable = 0

[tex]\alpha =\frac{\omega_f-\omega}{t}[/tex]

[tex]\alpha =\frac{0-8.16}{45}[/tex]

[tex]\alpha =-0.1814 \;rad/s^2[/tex]

Calculation of torque by using inertia and angular acceleration:

[tex]\tau = I\alpha[/tex]

[tex]\tau =1.2 \times 10^{-2} \times (-0.1814)[/tex]

[tex]\tau = 2.17\times 10^{-3} \; N.m[/tex]

Answer:

25.3 m/s

Explanation:

According to the laws of motion, the final velocity and the distance traveled by a particle moving at constant acceleration a m/s²  is given by the equation

[tex]v^2 = v_0^2 + 2a(x - x_0)[/tex]

where

v= final velocity m/s
v₀ = initial velocity m/s
x = final position m
x₀ = initial position m
a = acceleration in m/s²

x - x₀ is called the displacement, d

We are given
v₀ = 0 since particle is starting at rest
d = 80 m
a = 4 m/s²

Plugging these values into the above equation.

v² = 0 + 2 x 4 x 80 m²/s²

v² = 640 m²/s²

v = √640  = 8√10 ≈ 25.3 m/s
