السلام عليكم

we have a system of two particles of masses m1=m0 and m2=2m0 ,the magnitudes of their velocities are equal v1=v2=v0 . the two particles collid with each other in completey inelastic collision , where the direction of velocities are shown in fig


a-what are the velocity and the angle of deflection of the composite body resulting form collision?1

b-what is the velocity of the composite in CM-system

c-show that the total linear momentum of the system before and after the collision is zero in CM-system?3
