4. A lorry of mass 32,000 kg is travelling at a velocity of 24.0 m s when it collides into the back of a stationary car of mass 2600 kg. After the collision the lorry and car move off together and come to rest after a distance of 53.0 m. a) Determine the kinetic energy of the lorry immediately before the collision. [2] b) Determine the velocity of the lorry and car immediately after the collision. [2] Determine the loss of kinetic energy during the collision. [2] Determine the resultant force acting to slow down the lorry and car after the collision, assuming that the resultant force has a constant magnitude until the two vehicles come to rest. [2] c) d) 4. A lorry of mass 32,000 kg is travelling at a velocity of 24.0 m s when it collides into the back of a stationary car of mass 2600 kg.
