WebThe forces on the crate are its weight and the normal and frictional forces due to contact with the truck bed. We start by assuming that the crate is not slipping. In this case, the … WebMay 8, 2010 · 16. 1. As the lorry brakes, it undergoes a certain acceleration directed backwards. This means the surface of the flatbed wants to slide backwards under the crate. Friction tries to prevent this, by making the crate decelerate at the same rate as the lorry. However, this only happens up to a certain point where friction becomes insufficient.
WebA flatbed truck is carrying a 20.0-kg crate along a level road. The coefficient of static friction between the crate and the bed is 0.400, and the coefficient of kinetic friction is 0.300.
