3. A 50 kg cart is moving across a frictionless floor at 2.0 m/s. A 70 kg boy, riding in the cart, jumps off so that he hits the floor with zero velocity. a. Write the momentum conservation equation in terms of variables (m,v). b. What was the velocity of the cart after the boy jumped? BEFORE mg=70 AFTER mc=50 mg=70 v=2 V'=0 mc=50 Vc = ? 3.
