A 0.5 kg hockey puck slides across the ice starting with a velocity of 5 m/s. The puck slides and slows for 100 meters under constant acceleration and then stops.
a. What is the acceleration of the hockey puck?
b. What Kinetic Frictional Force is needed?
c. What is the co-efficient of friction between the ice and puck?
d. Recalculate a, b &c for a 1 kg hockey puck. (Does the weight change a or c?)
