Question

A ball is dropped from a height of 80m. When it reaches the ground, its velocity is v m/s. Find its velocity. (Take g= 10m/s2)

Answer 1

here is your answer ..

cheak whether is correct...

Answer 2

Answer:

On the ball a gravitational force will act on it

Hence we can apply a formula v^2-u^2=2as

Where v=final velocity u=initial velocity

a=g(acceleration)

So apply

V^2-0^2=2×10×80

V=40m/s ans..
