Question

a child drop a ball from a height of 10 metres assume that its velocity increases uniformly at the rate of 10 ms

find
the velocity with in which the ball strikes the ground the time taken by the ball to reach the ground ​

Answer 1

using v^2-u^2=2as

u=0

v^2= 2×10×10

$v = 10 \sqrt{2}$
