Dump Tower is 96 stories tall. A small, 0.6-kg object is dropped over the side of the roof of the tower and accelerates toward the ground. Track the object for its entire fall. Each story of this tower is 3.01 meters tall. What is the accelertion due to gravity of the planet and what is the impact speed of the object you dropped? Note: Time of fall is 12.60s

Explanation:

height of one floor = 3.01 m

height of 96 floor h = 96 x 3.01 = 288.96 m

time of fall t = 12.6 s

h = 1/2 g x t²

288.96 = 1/2 x g x 12.6²

g = 3.64 m /s²

v = u + gt

v = 0 + 3.64 x 12 .6

= 45.86 m /s

velocity of impact = 45.86 m /s .

the answer is a. hope this .

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
