Q) Two hockey pucks of equal mass undergo a collision on a hockey rink. One puck initially at rest while the other is moving with a speed 5.4 m/s. After the collision, the velocities of the pucks make angles of 33 and 46 relative to the original velocity of the moving puck. a) Draw a diagram showing the initial and final situation. You can upload your drawing by attaching it to this question. b) Determine the speed of each puck after the collision. Q) A simple pendulum (M1=0.21 kg) of length 0.65 m, is held 72 from the vertical as shown in the diagram below. The pendulum is released from rest so that at the bottom of the swing it undergoes an elastic head-on collision with a ball (M2=0.30 kg) that is travelling towards the first mass with a velocity of 1.0 m/s. 0.65m 720 0.65m M1 M2 M1 1.0 m/s a) What is the speed of the pendulum bob (M1) just before the collision? b) What is the speed of each mass just after the collision? (If you cannot do part a, choose a speed of 2m/s for MI for part b!!! )
