A 125 kg cyclist is moving along a mountain bike trail with a velocity of 13 m/s [E]. A force of 78 N accelerates the cyclist and bike for 5.75 seconds. What is the final momentum of the cyclist and bike?

Two dynamics carts (a type of cart used in physics experiments) undergo a head on, elastic collision. The first cart has a mass of 4.1 kg and an initial speed of 1.8 m/s [right]. The second cart has a mass of 2.7 kg and an initial speed of 0.90 m/s [right]. Determine the final speeds of the two carts.

A 30.00 kg mass falls from a height of 2.000 m. The magnitude of the momentum of the mass just before it hits the ground is
