If a boat is sliding down an angled boat ramp to the edge of a lake, how can the acceleration of the boat be decreased while keeping the net force of the boat/ramp system zero? Explain your answer in one or two sentences
To decrease the acceleration of the boat while keeping the net force zero, the friction between the boat's hull and the ramp needs to be increased. This can be achieved by various means, such as using a rougher surface on the ramp or applying additional downward force on the boat.
