Question

Particle ‘1’ of mass ‘m’ initially moving in the positive x-direction with speed V1i collides with the particle ‘2’ of mass m2 = m/3 moving in opposite direction of particle ‘1’ with unknown speed V2i as shown in figure. Assume no external force is acting upon the particle and don’t assume the elastic collision. After the collision, the particle ‘1’ moves in negative y-direction with speed V1f = V1i /2 and particle ‘2’ moves at angle 45o with the positive xdirection. Determine the speed of particle ‘2’ before and after collision and confirm collision is elastic or inelastic

Answer 1

Answer:

Multiply the second object's mass by its velocity. For example, if it weighs1,000 and has a velocity of -30 meters per second, then its momentum will be 30,000 kg meters per second. Add the two velocities together to determine which way the objects will move after collision.
