9. A salvage boat uses its winch to pull up a sunken treasure with an upward force of 4000 N. The mass of the treasure is 200 kg and the water exerts a force of 1500 N on the treasure, resisting the force exerted by the winch . The boat is directly above the treasure. Draw a free-body diagram for the treasure , calculate the acceleration , and predict the time dependence of the motion of the treasure, initially at rest.
