Question

Q-5.A child drops a ball from a height of 10m.Assume that its velocity increases uniformly

at the rate of 10 m/s2.Find ?
pls tell​

Answer 1

Explanation:

If the ball is dropped gently, we consider initial velocity to be 0.

u=0

We have equations of motion which are valid here because of constant acceleration.

2as=v2−u2

Just putting values as in your case

2⋅10⋅10=v2−02

200=v2

10√2=v

Now using v=u+at

10√2=0+10t

t=√2 sec
