a hockey stick is swung through an angle of 40 degrees in 0.06s from the top of the swing to the bottom of the swing. it starts from rest and the length of the stick is 1.45m. the stick has a mass of 700g and can be modeled as a long thin rod that would rotate at the end.

a) what is the angular velocity of the stick right before it hits the puck?

b) what is the velocity of the club head right before it hits the ball?

c) what is the radial (centripetal) acceleration of the head of the stick?

d) if 80 percent of the club's kinetic energy is transferred to the puck (155 g) what is the speed of the puck right after it is hit?

e) if the puck is in contact with the club for 3ms, and the puck starts from rest, what is the maximum force on the puck?
