Question

a child drops a ball from a height of 5 m/s²and that its velocity increases uniformly at the rate of hundred metre per second square find the velocity with which the ball strikes the ground​

Answer 1

A child drops a ball from a height of 5 m/s²and that its velocity increases uniformly at the rate of hundred metre per second square find the velocity with which the ball strikes the ground

Initial velocity = 24

Final velocity = ?

Height = 5 sec

Time = ?

a = 100 m/s²

Formula used :-

V2 = u² +2as

v = u + at

_________________

v² = 0² + 2×100×5

v = √ 1000 m/s

= 10√10 m/s

t = √10/10 = 1/√10 sec
