A hockey puck slides on the ice with an initial velocity of vi1= 5 m/s in the positive x direction. A second hockey puck issliding to the left with an initial velocity of vi2 = 3 m/s. Thetwo pucks collide and after the collision puck 1 has a finalvelocity of vf1 = 3 m/s in the positive x direction at an angle of30 degrees above the positive x axis. Is the collision elastic orinelastic?
Please show all work.
