- Problem 1: Two billiard balls with the same mass m move towards one another. Ball one moves in the positive x-direction with a speed of v11, and ball two moves in the negative x-direction with a speed of v2i. The two balls collide elastically, and both balls change direction after the collision. Vli If the initial speeds of the balls were vii = 2.0 m/s and v2i = 1.0 m/s, what would be the final speed and direction of ball two, v2f, in meters per second? Ov2f = 0 m/s. Ov2f = 2.0 m/s, in the negative x-direction. Ov2f = 2.0 m/s, in the positive x-direction. Ov2f = 1.0 m/s, in the positive x-direction. Ov2f = 1.0 m/s, in the negative x-direction.Box 1 is sitting at rest. Box 2 is moving to the left when it collides elastically with Box 1 (see figure). The surface is frictionless.

- A block of mass m = 3.5 kg, moving on a frictionless surface with a speed Vmo = 6.2 m/s makes a sudden perfectly elastic collision with a second block of mass M, as shown in the figure.

Just after the collision, the 3.5-kg block recoils (moves left) with a speed of Vm1 = 1.5 m/s and the unknown mass block moves right with a speed of VM1 = 2.1 m/s. What is the mass M of the second block? m M m M before afterA 0.60 kg ball is thrown horizontally at 20 m/s in the -x direction and collides with a 5.0 kg box which is at rest on a frictionless floor.
