A 10 kg medicine ball is thrown at a velocity of 15 km/hr to a 50 kg skater who is at rest on ice. The skater catches the ball and subsequently slides with the ball across the ice. Consider the skater and the ball as two separate parts of an isolated system. Based on conservation of momentum, fill in the momentum chart. Do NOT include units. Include a negative sign where appropriate. Momentum Before Collision Momentum After Collision Momentum Change Ball 1 4 Skater 2 8 Total
