If both the car B of mass M B and the jeep A of mass M A are free to roll, determine their velocities at the instant they meet. If the rope is of length L , how long will this take? Units Used: Mg 10 3 kg = Given: M A 2.5 Mg = v rel 2 m s = M B 1.25 Mg = L 5m = Solution: Guess v A 1 m s = v B 1 m s = Given 0 M A v A M B v B + = v A v B
