A minibus of mass 2000kg traveling at a constant velocity of 36km/h collides with a stationary
car of mass 1000kg. The impact takes 2 seconds before the two move together at a constant
velocity for 20 seconds. Calculate:
(i) The common velocity
(ii) The distance moved after impact
(iii) The impulse force
(iv) The change in kinetic energy

i)Momentum before collision = momentum after collision 1mk)
(2000 x 10) + (1000 x 0) = (2000 + 1000)V
3000V = 20000
V= 62/3m/s
