A car of mass 800 kg moves to the east with a speed of 20 m·s−1 . It collides with a truck that is also moving to the east with an initial speed of 10 m·s−1 . After collision, the car and the truck move together. If the mass of the truck is twice the mass of the car, calculate the amount of kinetic energy lost
