Question

A puck of mass mA that is moving along the +x axis with speed va collides with another puck of mass mB = 2mA. The collision is not head-on, so that after they collide, mB is located at 45◦ south of east, while mA collides head-on elastically with a stationary puck of mass mC = 3mA. If, after the second collision, the final velocity of mC is 0.450 [m/s], 25◦ north of east, what is the initial speed va?

What the puck! A puck of mass ma that is moving
along the +x axis with speed Va collides with another
puck of mass mB = 2m4. The collision is not head-on,
so that after they collide, mB is located at 45° south of
east, while ma collides head-on elastically with a station-
ary puck of mass mc = 3mĄ. If, after the second colli-
sion, the final velocity of mc is 0.450 [m/s], 25° north of
east, what is the initial speed v.?
A. 0.540 [m/s]
В. 1.80 [m/s]
C. 1.20 [m/s]
