A car of mass 1200kg traveling with a velocity of 30 meters per second collides head on into a stationary car which has a mass of 800kg.After the impact the two vehicles lock together and move in the same direction as the 1200kg car.
(i) What is the velocity of the cars after the impact?
(ii) What is the loss in kinetic energy?
Additional information
The problem related to Physics and it discusses about calculation of velocity of cars after impact and the loss in kinetic energy.
