Two wooden pucks approach each other on an ice rink as shown in the figure. Puck #2 has an initial speed of 4.14 m/s and a mass that is some fraction f = 2 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 13.2% 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.

The mass of the blue puck shown below is 35.0% greater than the
mass of the green puck. Before colliding, the pucks approach each
other with momenta of equal magnitudes and opposite directions, and
the green puck has an initial speed of 11.0 m/s. Find the speeds
the pucks have after the collision if half the kinetic energy of
the system becomes internal energy during the collision.

Two particles approach each other with equal and opposite speed
v. The mass of one particle is m, and the mass of the other
particle is nm, where n is just a unitless number. Snapshots of the
system before, during, and after the elastic collision are shown
above. After the collision the first particle moves in the exact
opposite direction with speed 2.40v, and the speed of the second
particle is unknown. What is the value of n?
