A speedboat is moving at a constant speed, and the force propelling it forward is balanced by the force of the water pulling it backward. But suddenly a wave strikes it from the side with a force of 500 newtons. When the wave hits the boat, A. the speedboat's direction of motion will change. B. a net force of 4,000 N will act on the speedboat. C. a net force of 8,000 N will act on the speedboat. D. the forces acting on the speedboat will stay balanced.
