Momentum

A 50 kg ball rolls down the street at 5 m/s. Calculate the momentum of the ball. 

• 55 kg*m/s
• 100 kg*m/s
• 250 kg*m/s
• 500 kg*m/s

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...

• Skater 1 experiences a greater change in momentum

• Skater 2 experiences a greater change in momentum

• Skater 1 has a greater speed than Skater 2

• Skater 1 experiences a greater force
