2 Two wooden pucks approach each other on an ice rink as shown in the figure. Puck #2 has an initial speed of 4.28 m/s and a mass that is some fraction f = 3 that of puck #1. Puck #1 is made of a hard wood and puck #2 is made of a very soft wood. As a result, when they collide, puck #1 makes a dent in puck #2 and 16.2% of the initial kinetic energy of the two pucks is lost. Before the collision, the two pucks approach each other in such a manner their momentums are of equal magnitude and opposite directions. Determine the speed of the two pucks after the collision. V1f= V2f= m/s m/s Puck #1 40 40° D 110
