The driver of the truck suddenly applies its brakes, and the truck comes to a stop under the action of a constant braking force. During braking, either the crate slides or it does not. Considering the work-energy principle applied to the truck during braking, will the truck stop in a shorter distance (or time) if the crate slides, or will the distance (or time) be shorter if it does not? Assume that the truck bed is long enough that you don’t have to worry about whether or not the crate hits the truck. Justify your answer.
