Question

Two disks collide with the initial velocities just before the collision as shown in (Figure 1).

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 e = 0.9? The masses of the disks are m_A = 5 kg and m_B = 7.5 kg, the initial velocities are v_A = 3 m/s and v_B = 3.2 m/s and the angles shown are θ_A = 33° and θ_B = 54°

Part A

What is the final velocity of disk A in the x-direction?

Part B

What is the final velocity of disk A in the y-direction?

Part C

What is the magnitude of the velocity of disk A after the collision?

Part D

What is the final velocity of disk B in the x-direction?

Part E

What is the final velocity of disk B in the y direction?

Part F

What is the magnitude of the velocity of disk B after the collision?
