3a A 170 g hockey puck has an inelastic collision with a moving zamboni. The puck approaches at 12 m/s, 30 deg to the normal. It bounces back at 8 m/s, 45 deg from the normal. The interaction with the zamboni lasts 20 ms. What is the average force that the zamboni applies to the puck? Make the normal to the zamboni surface the y-axis and assume the puck is initially moving with positive - and y-components.
