Question

A ball is gently dropped from a height of 20 m. If its velocity
increases uniformly at the rate of 10 ms?, with what velocity will it strike the ground?after what time will it strike the ground ​

Answer 1

Answer:

20m/s

Explanation:

u = 0 m/s

a = 10m/s^2

s = 20m

v^2 = u^2 + 2as

v = sqrt( 0^2 +2*10*20)

v= sqrt(400)

v= 20m/s
