Question

A stone is released from the top of a tower of height 30 m. Calculate its final velocity just before touching the ground

Answer 1

Answer:

velocity - 10√ 6 m/s

Explanation:

initial velocity = 0 m/s

final velocity = we have to find (?)

Height = 30 m

now,

v² = u² + 2gh

v² = ( 0 )² + 2 ( 10 ) 30

v² = 600.

v = 10 √ 6 m/s ...Ans
