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 = 5.80 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of ? = 34.0° with the horizontal axis while the green disk makes an angle of ? = 56.0° with this axis as in Figure b. Determine the speed of each disk after the collision.
In the figure, two particles are launched from the origin of the coordinate system at time t - O. Particle 1 of mass m₁ - 5.20 g is shot directly along the x axis (on a frictionless floor), where it moves with a constant speed of 10.7 m/s. Particle 2 of mass m₂ -4.50 g is shot with a velocity of magnitude 15.6 m/s, at an upward angle such that it always stays directly above particle 1 during its flight.

Treat the collision as elastic. A moving billiard ball hits an identical (except for color) stationary ball. After the collision, the orange ball always goes off in the positive x-direction. The final speeds are v and V. Calculate the angle θ that the green ball goes off in. (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.
A 180-g billiard ball is shot toward an identical ball at velocity vi = 6.90 m/s. The identical ball is initially at rest. After the balls hit, one of them travels with velocity v1, f = (1.80 + 2.22) m/s. What is the velocity of the second ball after the impact? Ignore effects of friction during this process. (Express your answer in vector form.) v2, f = m/s
