Q1. One of the air puck of 15m, kg mass is moving to the right with a speed of 8v, m/s. The other air puck Two air puck is moving along x-axis on an air hockey table, which is frictionless and horizontal. of 30m, kg mass is moving to the left with a speed of 22v, m/s. They collide head-on through an elastic collision then, a) Find the final velocity (the magnitude and the direction) of each air puck. b) Confirm the kinetic energy of the system is conserved. V = +8v, m/s V2i = -22v, m/s +x
