A particle A of mass 0.1kg is moving at a speed of 1.5m/s to the right. It collides with a particle B of mass 0.3kg moving at a speed of 1.1m/s to the right. Calculate change in momentum of particle A if particle B has a speed of 1.4m/s after collision.

Momentum is conserved during the collision.Momentum = mass x velocityMomentum before = momentum after(mv) P1 + (mv) Q1 = (mv) P2 + (mv) Q2 (0.1 x 1.5) + (0.3 x 1.1) = 0.1v P2 + (0.3 x 1.4)v P2 = 0.6m/sChange...
