1. Ryan is readying for a face-off at the begninning of a hockeygame. What is the total Force that ryan exerts on the ice? What isthe total force of the ice on Ryan? Assume that Ryans total mass is100 kg. Also take up ot be the +y direction, and towards theopponents goal to be +x direction.

2. Ryan is skating down the ice at 5 m/s. What is Ryan'smomentum? Kinetic Energy?

3. Preparing to take a shot at the net, Ryan comes to a stop onthe ice. If it takes ryan .5 seconds to come to stop, what is thenet force that the ice exerts on Ryan? Use the net force to findthe distance it takes ryan to come to a stop. What is the net forcethat Ryan exerts on the ice while stopping: give a name to thisforce.

4. Ryan takes a shot, sending the .2 kg puck towards the goal at30 m/s. Assuming the collisions with the net are perfectlyinelastic, and the collisions with the goalies stick are perfectlyelastic, and that the goalie and net both remain at rest after thecollision calculate:
a. The change in kinetic energy and momentum if the goalieblocks the puck with his stick
b. The change in KE and momentum if the puck goes into the netand stops.
