Solved Problem: Larry has a mass of 80 kg and runs across the front of the classroom with a speed of 4 m/s and jumps onto d The skateboard is initially at rest and a mass equal to Larry's. If friction with the floor is negligible, what is the speed of Larry and the skateboard after he jumps on board? Known: m = 80 kg, v, 4 m/s, m, = 80 kg, v = 0 m/s, Find the speed of Larry and the skateboard after the "collision." Principle: Momentum is conserved in an inelastic collision.
