Problem
A cart is initially moving toward the right along a horizontal track but is slowing down because of a constant kinetic friction force that acts toward the left. Describe the direction of the cart’s acceleration and explain, in one or two sentences, why the acceleration is not in the same direction as the cart’s velocity.
