Abox sits on the back of a flatbed truck. if the coefficient of static friction between the box and the truck bed is μs = 0.400, what is the shortest distance in which the truck can stop on level ground without the box sliding if it is initially traveling at v = 15.0 m/s?

28,699m

Explanation:

The force to make the box move should be μs.N=μs.m.g=m.|a|

then,

|a|=μs.g

Being

μs coefficient of static friction,

N the force made by the truck on the box caused by the gravity force,

m the mass,

g the acceleration of gravity

and a the acceleration of the truck.

as the truck is stopping, the acceleration is negative. then,

28,699m
