A 0.15 Kg hockey puck is struck by the stick, and the velocities before and after impact are shown in the figure. If the puck is in contact with the stick for 6 ms, find the xcomponents of the average impact force by the stick on the puck. x y υ 1 = 10 m/s 2 = 20 m/s 20 ° 55 ° _________ 51.9 N __________ 3. Two spheres A ( m A = 4 Kg) and B ( m B = 6 Kg) are traveling toward each other as shown in the figure. (a) If the two spheres make an elastic collision, find the change of momentum of sphere A . _______ − 38.4 Kg·m/s _________ A B 6 m/s 2 m/s (b) If the two spheres stick together after the collision, find the percent energy loss. _______ 91.4 % _________...
