Question

A body fall from rest with an acceleration of 10m/s?what is the velocity after 5s? ,how far has it fallen by then

Answer 1

Since the acceleration is constant

So we use the 1 equation of motion for constant acceleration

Vf=Vi+at

Since the ball is at rest

Then Vi=O

Vf=O+10(5)

Vf=O+50

Vf=50m/s
