Answer» Given : starting from rest a car is moving with uniform acceleration To Find : what happens to the displacement covered if time of travel is DOUBLED? Solution: S = ut + (1/2)at² S = Displacement u = initial velocity a = acceleration t = time Let say t = T u = 0 as start from rest S =0 + (1/2)aT² => S =(1/2)aT² if time is doubled t = 2T => S = 0 + (1/2)a(2T)² => S = 4((1/2)aT²) Displacement will be 4 times if time is doubled Learn More: The acceleration displacement graph of a particle moving in a ...
