Question

a) The time taken for an object to reach the earth's surface when dropped from a
height is equal to the time taken for an object to reach the surface when dropped
from the same height on Mars. Is this statement correct? Justify your answer.​

Answer 1

Explanation:

Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
