5. A speed boat is cruising in the ocean. It has an upward force (buoyant force) of 5000N acting
on it, a weight of 5000N, and a force of 20,000N coming from its engine. If the boat is
accelerating forward, what must be the fluid friction on the boat caused by water, if the net
force on the boat is 4000N to the right?
b. Draw a free-body diagram showing the boat in the water.
