A particle (M1 = 1.47 kg) moving at 30.0° downward from the horizontal with v1 = 2.53 m/s hits a second particle (M2 = 3.47 kg), which is at rest. After the collision, the speed of M1 is reduced to 0.541 m/s, and it is moving at an angle of 32.0° downward with respect to the horizontal. You cannot assume that the collision is elastic. What is the speed of M2 after the collision?
