Problem Statement | A delivery van is driving along a horizontal road. The truck could be moving at a constant speed, or accelerating in either the forwards or backwards direction. A box (m₂) in the back of the van is up against the front end of the cargo area, not sliding on the wall. If the van was not accelerating, the box would slide downwards. There is fric- tion between the box and the wall. For all parts of this question, analyze the situation as if you are standing on the Earth watching this van and box move in front of you. (a) Describe with words, diagrams, etc... two scenarios of the van's motion that could result in the box not sliding relative to the wall, as shown in the figure. (b) Sketch a FBD of the box system for one of the scenarios you described in part (a). (c) What is the minimum acceleration of the box such that the box does not slide down the cargo area wall? The coefficient of static friction between the box and the wall is 0.750 m₁ Problem Statement | A delivery van is driving along a horizontal road.
