Two hockey pucks slide along a flat sheet of ice with no friction, and then collide with each other. The diagram below shows a top-down view of the colliding hockey pucks. The masses of the hockey pucks are mA = 2.00 kilograms (kg) and mg = 1.50 kg. Before the collision, puck A moves to the right at a speed of 2.50 meters per second (m/s) and puck moves to the left at a speed of 1.25 m/s. After the collision, puck A moves at a speed of 1.00 m/s at 50.0 degrees relative to the x axis. 1.00 m/s 2.50 m/s 50.0° A 1.25 m/s A before collision after collision (a) Find find the final speed (in m/s) of puck B after the collision.
