A hockey puck moving at a speed V1A on a frictionless surface collides head on with a second identical puck moving toward it at speed V2A. After the collision the first puck slows down to speed V1B without changing direction. a. Derive an equation for the velocity V2B of the second puck after the collision. b. Calculate the velocity v2B of the second puck was 12.0 m/s. Both pucks have a mass of 0.16 kg. c. Do your answers change if the masses of both pucks are doubled?

    A 1.25kg hockey puck (puck A) slides across a frictionless sheet of ice and collides with a puck of unknown mass (puck B) head on. The collision is completely elastic, which means no kinetic enegy is lost in the collision. After the collision, puck A moves in the opposite direction at half of its initial speed. Find the mass of puck B.

    A hockey puck, mass 0.24 kg, travelling with a speed of +20 m/s. collides with another stationary puck of exactly half the mass, hitting it head-on, but instant superglue makes the pucks stick together. The collision is perfectly inelastic and one dimensional. Ignore any friction with the ice they are travelling on. Calculate the total momentum of the two-puck system both before and after the collision.
