A block of mass 0.50 kg is moving with a speed of 2.00 cm^(-1) can a smooth surface . It strikes another mass of 1.00 kg and then they move togather as a single body . The energy less charing the collision is

A block of mass 0.50 kg is moving with a speed of 2.00 m/s on a smooth surface. It strikes another mass of 1.00 kg and then they move together as a single body. The energy loss during the collision is

An empty truck of mass 1000 kg is moving at a speed of 36 km h^(-1) . It is loaded with 500 kg material on its way and again moves with the same speed. Will the momentum of the truck remain the same after loading? If not, find the momentum of the truck after loaded.
