Question

A stone is dropped from top of a tower. If it takes 6 sec to hit the ground, find the height of tower and velocity with which the stone hits the ground ?​

Answer 1

Answer:

Explanation:

s = ut+ 0.5at²

u = 0

t = 6

a = 9.81

s = 0 + 0.5 * 9.81 * 36 = 176.58 m

v = u + at

v = 9.81* 36 = 353 m/s
