Learning Goal: To use the conservation of momentum and the coefficient of restitution to determine the speeds of two disks after a collision. Two disks collide with the initial velocities just before the collision as shown in (Figure 1). What are the speeds of the two disks just after impact if the coefficient of restitution is = 0.57 The masses of the disks are m=5 kg and my=7 kg.the initial velocities are 3.3 m/s and R = 5 m/s and the angles shown are 28" and @g=67 What is the final velocity of disk in the z-direction?
