Question
Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at voi = 6.05 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 8 = 38.0° with the
horizontal axis while the green disk makes an angle of = 52.0° with this axis as in Figure b. Determine the speed of each disk after the collision.

A railroad car of mass 2.85 x 104 kg moving at 3.10 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s.
(a) What is the speed of the three coupled cars after the collision?
m/s
(b) How much kinetic energy is lost in the collision?
