Puck 1 (0.5 kg) travels with velocity 80 m/s to the right when it collides with puck 2 (2 kg) which is initially at rest. After the collision, puck 1 moves with a velocity of -16 m/s. Assume that no external forces are present and therefore the momentum for the system of pucks is conserved. What is the final velocity (in m/s) of puck 2 after the collision? Submit Answer Tries 0/2 A kid runs towards the edge of a merry-go-round that is not rotating and jumps on. The merry-go-round then rotates with a constant angular velocity w. Assume that the kid has a mass of 20 kg and is initially running at a speed of 2 m/s tangent to the edge of the merry-go-round.
