Consider the collision of a moving puck with a second, initially stationary puck, as shown in the figure. According to the law of conservation of momentum m¡v] = m¡Vif+m2V2f where m1 = 0.50 kg is the mass of the first puck with initial velocity vif and final velocity v2f, and m2 = 0.60 kg is the mass of the second puck with outgoing velocity v2f. Assume the incoming velocity of the first puck is along the x-axis and the outgoing velocity of mass m¡ is at angle 01 = 50°. Suppose the initial speed of mass m¡ is v = 1.5 m/s and the final speed of mass m is vif=0.5 m/s. Mass m2 leaves at angle 02 with respect to the x-axis and you will need to find this angle as part of this problem. %3D %3!

Consider the collision of a moving puck with a second, initially stationary puck,
as shown in the figure. According to the law of conservation of momentum
2+ vןmmyvy =
where mj = 0.50 kg is the mass of the first puck with initial velocity vif and final
velocity v2f, and m2 = 0.60 kg is the mass of the second puck with outgoing
velocity v2f. Assume the incoming velocity of the first puck is along the x-axis
and the outgoing velocity of mass mj is at angle 01 = 50°. Suppose the initial
speed of mass mj is vi = 1.5 m/s and the final speed of mass mj is vif=0.5 m/s.
Mass m2 leaves at angle 02 with respect to the x-axis and you will need to find
this angle as part of this problem.
