Question

(a) using velocity - time graph derive : V^2 - u^2 = 2as (b) A ball is gently dropped from a height of 20m. if its velocity increases uniformly at the rate of 10 m/s, with what velocity will it will strike the ground?​

Answer 1

Answer:

Ball strike the ground with 20 m/s

Explanation:

As from third equation of motion

Put u= 0 g=10 h=20 in third equation of motion
