Two hockey players( one of mass 10 kg, and the other of mass 15kg) are skating and collide and stick together.? the velocity of the first sketer is 10 m/s, the other is 17 m/s. what is their speed at the moment of the collision? question: is there a difference between after the collision and at the moment of the collision? is it not the same?
