A bullet of mass 10.0 g is fired into an initially sta -tionary block and comes to rest in the block. The block, of mass 1.00 kg, is subject to no horizontal external forces during the collision with the bullet. After the collision, the block is observed to move at a speed of5.00 m/s.(a) Find the initial speed of the bullet.(b) How much kinetic energy is lost

Consider a system with two masses that are moving away from each other. why will the kinetic energy differ if the frame of reference is a stationary observer or one of the masses?
