Question

a vehicle starts from rest and attains a velocity of 86km/hr in 8 minutes assuming the acceleration to be uniform find (1) acceleration (2) the distance coverd

Answer 1

86km/h = (215/9) m/s and 8min=480sec ; therefore acceleration (a)=v/t =0.05m/s^2 :
distance coverd = v*t = 11466.66m or 11.46km
