Problem
A sled is pulled across level snow by a constant horizontal force F, causing it to accelerate at a rate a. The coefficient of kinetic friction between the sled and the snow remains unchanged. Suppose both the sled’s mass and the pulling force are doubled. State whether the sled’s acceleration increases, decreases, or stays the same, and explain your reasoning in one or two sentences.
