Homework Statement
A jet-powered flatbed truck has a crate of mass m, which is strapped down to the truck with a tension three times the weight of the box. Find the maximum acceleration without having the box slide. Us= .9, Uk=.7
Homework Equations
Fun= SUM
Fun= ma
Ff= -(Us) Fn
The Attempt at a Solution
I've figured out the Y components, and resulted in the Ff= 35.3m, my only problem now is where to go from here. I can't for the life of me figure out the other horizontal force other than Ff.
when I attempt the solution, I get
Fun=SUM
= Ff
=35.3m
Fun=ma
35.3m=ma
35.3=a
I know the answer is -7.7 but I can't seem to think of the opposing horizontal force.
