(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A box with a mass of 5 kg sits in the middle of the bed of a pickup truck moving with a speed of 90 km/h. The maximum force of friction between the box and the truck is 15N. If the truck were braked uniformly to a stop in 125 m, would the box move? Justify your answer mathematically.

2. Relevant equations

vf2= vo2 + 2ax???

3. The attempt at a solution

a= (vf2 - vo2) / 2x

a= (0-9) / 2(125)

a= -0.36

yes is would

am i even close?
