1. The problem statement, all variables and given/known data you and your friend have just loaded a 200kg crate filled with priceless art object into the back of a 2000kg truck. As you press down on accelerator, a force, Ft, propels the truck forward. What is the max magnitude the force can have without the crate sliding? The static and kinetic coefficient of friction between the crate and the bed of the truck are 0.8 and 0.3. 2. Relevant equations 3. The attempt at a solution Here is what i have for my FBD The crate: >normal force acting up >gravitational force acting down >static force acting to the right The truck: > Ft acting to the right >gravitational force acting down (includes both the weight of the crate and the truck) >normal for acting up I think that as the truck accelerates to the right the crate would want to slip to the left, and the friction would oppose this motion (acting to the right) and stops the sliding. but can someone explain how i can connect the two FBD to relate Ft to the friction force?
