A 6.43 kg ball moving initially at 10.8 m/s hits a 6.14 kg ball at rest, in a linear elastic collision. What is the speed of the first ball after the collision? (the one initially moving)     What is the speed of the second ball after the collision? (the one initially at rest)

A billiard ball is moving in the x-direction at 30.0 cm/s and strikes another billiard ball moving in the y-direction at 40.0 cm/s. As a result of the collision, the first ball moves at 50.0 cm/s, and the second ball stops. What is the change in kinetic energy of the system as a result of the collision?

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. Voi = 3.15 m/s as in Figure The green disk is initially at rest and is struck by the orange disk moving initially to the right at v a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 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. X V of Vgf= 1.66 Your response differs from the correct answer by more than 10%. Double check your calculations. m/s m/s a Before the collision After the collision b
