PLEASE HELP
Puck 1 is moving 10 m/s to the left and puck 2 is moving 8 m/s to the right. They have the same mass, m.

A. What is the total momentum of the system before the collision? (Write your answer in terms of the mass, m.) (0.5 points)
B. What is the total momentum of the system after the collision? (Write your answer in terms of the mass, m.) (0.5 points)
C. Write puck 1's velocity after the collision in component form. (1 point)
D. What is the y-component of puck 2's velocity after the collision? (1 point)
E. What is the x-component of puck 2's velocity after the collision? (1 point)
F. At what angle does puck 2 move after the collision? Determine the angle and draw it on the diagram. (1 point)
G. What is the magnitude of puck 2's velocity after the collision? (1 point)
