A ball of sticky wax has a mass of 0.25 kg and a velocity of 12 m/s right before it collides with the floor. It just crushes into the floor and sticks with a velocity of zero. What is the change in momentum of this ball of wax? Give both the amount and the direction because momentum is a vector There are two forces are acting on the wax ball while it is coming to a stop and losing all its momentum. One of the forces is by the floor upwards on the ball of wax. The other force is due to gravity down on the mass of the wax. Which of these forces is stronger? Explain how you know.

A woman of mass m = 63 kg runs at a velocity vi = 1.53 m/s before jumping on a skateboard that is initially at rest. After jumping on the board the woman has a velocity vf = 1.42 m/s.b. What is the mass of the skateboard in kilograms? mb =c. The woman soon loses his balance and falls backwards off the board at a velocity of 1.0 m/s. Assuming momentum is conserved in this process, what is the skateboard's new velocity in meters per second? [Note: this may not be a very good assumption, as there can be significant friction in the ball bearings of the skateboard]
