Answer:
250 m
Explanation:
Given :
Initial velocity, u = 0
Acceleration, a = 5 m/s2
Time elapsed is t = 10 seconds
The distance traveled in 10 seconds by the particle when accelerating at 5 m/s2 is given by,
Putting the values,
x = 250 m
The particle moved 250 m in 10 seconds
The answer
<em>The temperature of substance B will increase more rapidly than the temperature of substance A will.</em>

Answer:
d. equal to one-fourth the acceleration at the surface of the asteroid.
Explanation:
The explanation is attached as a picture with this answer
Newton's law of universal gravitation is being used to compare the accelerations at the surface and at the top of the ball's path.
as it can be seen in the explanation that the proportional form of the equation is used because we do not need to necessarily use to final form with "G" for comparison calculations.
As per the given scenario only difference between the two points in the gravitational field is the distance from center of the spherical asteroid, i.e. r.
It is taken 2r for the top is the path. hence we obtain (1/4)g as our answer.
The centripetal acceleration is given by
where v is the tangential speed and r the radius of the circular orbit.
For the car in this problem,
and r=40 m, so we can re-arrange the previous equation to find the velocity of the car:
