A car initially at rest starts with a uniform acceleration and gains a velocity of twenty meter per second in four second the displacement of car is

Open in App

Solution

Initial velocity, u=0
Final velocity, v=20m/s
Time =4s
To find acceleration
V=u +at
20=0+a4
a=20/4
=5m/s^2

To find displacement
V^2-u^2=2as
20^2-0=25*s
400-0=10s
s=400/10
Displacement, s=40 meters
