A 90.0-kg ice hockey player hits a 0.150-kg puck, giving the puck a velocity of 45.0 m/s. If both are initially at rest and if the ice is frictionless, how far does the player recoil in the time it takes the puck to reach the goal 15.0 m away?
An alpha-particle undergoes an elastic collision with a stationary uranium-235 nucleus. What percent of the kinetic energy of the alpha-particle is transferred to the uranium nucleus? Assume the collision is one-dimensional.
Two hockey players of unequal masses collide with each other head-on, each moving at a speed of 15 m/s. After the collision, the hockey players move in the same direction as each other, each at the speed of 5.0 m/s. How many times greater is the mass of the more massive hockey player than the mass of the other hockey player?
