Particle A of mass m, initial velocity 20i (m/s) has a collisionwith a stationary particle B of mass 2m. After collision,VA(final)=10i+5j (m/s). a) Find VB(final) if the system (particle Aplus B) linear momentum is conserved (both i and j directions).What are the velocities of center of the system before and aftercollision?b) Find the system’s % KE lost due to the collision(m=20.0gram). c) If the collision time between A and B is 0.050 s,what is the average force between A and B during the collision?
