Ikjoo Yoo of the Tampa Bay Lightning has had his slap shot clocked at 102.1 mph (45.64 m/s). Assume that he shoots a 300 g puck that fast and that a stationary 91 kg goalie catches it while standing on frictionless ice.
A. How much momentum is lost in the collision?
B. What is the final speed of the goalie and puck?
C. What kind of collision is this when a goalie catches a speeding hockey puck?
D. How much kinetic energy is lost in the collision?
E. For practice, Modin has a wooden "goalie" rigged to a spring that is free to oscillate on the ice. The "goalie" has a mass of 40 kg. When he hits it with his special pucks that stick to the goalie, the apparatus oscillates with an amplitude of 0.20 m. What is the spring constant of the spring in the apparatus?
F. What is the maximum acceleration of the apparatus?
