A car accelerates from 6 ms–1 to 16 ms–1 in 10 sec. Calculate (a) the acceleration and (b) the distance covered by the car in that time.

Initial velocity = u


u = 6m/s


Final velocity = v


V = 16m/s


Time = t = 10 s


• Acceleration = a


a = (v-u) / t


= (16-6)/10


= 1 m/s2


• Distance = s


s =


s =


= 110 m
