A 1-kg hockey puck travelling 30km/h hits a massive wall at an angle of 01=30° from the wallI. a) Clearly draw coordinate system for the incoming velocity of the puck. In addition, define the normal and tangential directions as we did in class (this could be helpful on the same array as the incoming puck velocity). Include the necessary transformation arrays. b) Compute the final velocity of the puck after it hits the wall (in m/s). Express your answer in the normal and tangential coordinate system. c) What is the rebound angle (02) if the coefficient of restitution is 0.63?
