A small object of mass 0.50 kg traveling to the right at 4.0 m/s collides with a much more massive 10.0- kg object initially at rest and bounces off of it at a speed of 0.90 m/s. The collision is elastic. Assume that friction is so small that it may be neglected. Compare the total (combined) momentum of the two objects before the collision to their total momentum after the collision. Use numeric values.

INITIAL: FINAL: M. A white billiard ball with mass mw = 1.53 kg is moving directly to the right with a speed of v = 3.25 m/s and collides elastically with a black billiard ball with the same mass mb = 1.53 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of ew = 51° and the black ball ends up moving at an angle below the horizontal of Ob = 39°. %3D 1) What is the final speed of the white ball? m/s Submit 2) What is the final speed of the black ball? m/s Submit

A block of mass m = 5.0 kg, moving on frictionless surface with a speed vi = 10 m/s, makes a sudden perfectly elastic collision with a second block of mass M which is originally at rest, as shown in the figure.

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 22 m/s. The masses of the two objects are 3.1 and 7.1 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.
