A particle (M1= 1.13 kg) moving at 30.0° downward from the horizontal withv1= 2.43 m/s hits a second particle (M2= 3.13 kg), which is at rest. After the collision, the speed ofM1is reduced to 0.441 m/s, and it is moving to the left and downward at an angle of 32.0° with respect to the horizontal. You cannot assume that the collision is elastic. What is the speed of M2 after the collision?
