I'm out playing near a frozen pond. On the pond is a block of ice (initially at rest) with mass 17.0 kg . I slide a different ice block of mass 2.75 kg so that it collides with the stationary block. Just before impact (long after I stopped pushing it), the moving block has speed 6.25 m/s . Ignore friction with the pond. When the blocks collide they stick together and move off as a unit. Required:
What is the change ÎK=KfinalâKinitial in the block-snowball system's kinetic energy due to the collision?
