The two hockey pucks, A and B, on a frictionless surface are covered with Velcro. Both the pucks contain a mass of .50kg. Puck A is moving south at a speed of 1.2m/s and B is moving east at a speed of around 1.6m/s. The two collide and stick altogether.
i) Find out the initial momentum of the system made by the two pucks (direction, magnitude and units).
ii) Draw a single vector to symbolize the initial and final momentum of the system made up of two pucks.
iii) Find out the magnitude and direction of the velocity of the hockey pucks following to collision.
