Question

A body starts from rest and moves with uniform acceleration of 25 m/s2 what will be its velocity after 20 sec​

Answer 1

Answer:

Since the acceleration is uniform,

Velocity at 0 second = 0

Velocity at 1 second= 25m/s

Velocity at 2 seconds= 50m/s

Velocity at 5 seconds= 125m/s

We can also calculate the velocity as acceleration*time

=25m/s^2 *5seconds = 125 m/s

So, rhe velocity after 5 seconds is >125m/s
