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 net force of 8,000 N will act on the speedboat.
the forces acting on the speedboat will stay balanced.
the speedboat's direction of motion will change.
a net force of 4,000 N will act on the speedboat.
