Question

a child drops a ball from a height of 10m assume that it's velocity increases uniformly at the rate of 10m/s sq find the velocity with which it strikes the ground and time taken by ball to reach ground​

Answer 1

Answer:

Here, Initial velocity (u) = 0

Acceleration (a) = 10m/s²

Distance (s) = 50m

We need to find out the final velocity (v) .

By using, 2as = v² - u²

Putting the values we get,

2*10*50 = v²

V = 31.7 m/s appox is the ans.

Hope it will help you.

Thanks..:-)
