Question

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

Answer 1

Step-by-step 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 .
