A BB with a mass of 25g travels of 33m/s and strikes a clay ball which is at rest. The clay has a mass of 100g. If the collision is inelastic solve for the final velocity of the BB and clay.

A 70.0 kg ice hockey goalie, originally at rest, has a 0.280 kg hockey puck slapped at him at a velocity of 45.5 m/s. Suppose the goalie and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities Ugoalie and Upuck of the goalie and the puck, respectively, be in this case? Assume that the collision is completely elastic. Ugoalie = Upuck = Question Credit: OpenStax College Physics m/s m/s

A cart of mass 0.3kg traveling at 3m/s on a horizontal frictionless track collides with a cart of mass 0.45kg traveling at 2.5m/s towards it.  The carts stick together after the collision.  What is the final velocity of the carts

A fast car is speeding down a road with a velocity of v. It collides with a truck moving in the opposite direction that has a mass that is four times that of the fast car. They are both moving at the same speed. If the collision is elastic, then what are both of the vehicles velocities given as multiples of v.
