Question

A body initially at rest travels a distance 100m in
5s with a constant acceleration. Calculate : (1) the
acceleration, and (ii) the final velocity at the end of
5s​

Answer 1

Answer:

1) 4 m/s² 2)20m/s

Explanation:

1) speed = dis /time

100/5 = 20 m/s

final speed = 20 m/s

initial speed = 0 m/s

acceleration = V-U/t

20-0/5 = 4 m/s²

acceleration is 4 m/s²

2) final velocity is 20 m/s
