for those math geniuses, i have no idea where to even begin or start on this problem:
A 35kg box rests on the back of a truck. The coefficient of static friction b/w the box (mu s [mu static]) and the truck bed is 0.300.
a) when the truck accelerates forward, what happens to the box? (i'm guessing it stays where it is, doesn't move)
b) Find the max acceleration the truck can have before the box slides backward.
b is what i'm having trouble with, i know all the equations that i NEED to know for this question, it's just that i don't know where or how to even begin this question, it's the last question on this review sheet too (friction). HELP MUA PLEASE!!!!!!
