A car starting from rest picks up a velocity of 15m/s in 20 seconds. find the acceleration of the car.

As we know the relationship between final velocity and initial velocity.

V=u+ft

Here, v=final velocity =15m/s

U=initial velocity=0m/s=rest

f=acceleration
t=time=20sec

f=15/20 m/s^2=0.75m/s^2
