Question 2: Jack and Jill are maneuvering a 1000 kg boat near a dock. Initially the boat's position is (-14, 0, -20) m and its speed is 6 m/s. As the boat moves to position (12, 0, -14) m, Jack exerts a force (12, 0, 35) N and Jill exerts a force (21, 0, 50) N. Calculate the final speed of the boat.
