Coefficient of static friction

  • #1
A crate is in a pickup truck traveling horizontally at 15.0 m/s. The trucks apply the brakes for
28.7 m while stopping with uniform acceleration. What is the coefficient of static friction between the crate and the truck bed if the crate does not slide?


I know how to solve for the coefficient of static friction, but what I'm given in the problem doesn't make since with me to find the mass, normal force, or any of the other required components to find the coefficient of static friction. I'm completely at a loss as to where to begin, can anybody help me out?

Find the acceleration first. Draw a FBD on the block while moving on the truck, how is friction related to any of the forces you will have drawn?
