A truck with mass 1200kg is moving at 8m/s when it collides head-on with a stationary car of mass 800kg. As they collide, the vehicles move together with the same velocity, v. Calculate this velocity.
Momentum is conserved. MU + mu = (M+m)v (1200 x 8) + (800 x 0) = (1200 + 800)v 9600 = 2000v v = 9600/2000 = 4.8m/s
