1. The problem statement, all variables and given/known data The coefficients of friction between the load and the flat-bed trailer shown are [tex]\mu[/tex]s = 0.40 and [tex]\mu[/tex]k = 0.30. Knowing that the speed of the rig is 45 mi/h, determine the shortest distance in which the rig can be brough to a stop if the load is not to shift. The drawing shows a box sitting a top of a trailer bed with a distance of 10' between the box and the cabin. 2. Relevant equations 3. The attempt at a solution I am not really sure how to begin this problem. I am thinking using the coefficient of friction I can find the acceleration of the box and use that to find the distance needed for the truck to stop, but I am not sure. So far I have used the [tex]\mu[/tex]k to find the acceleration of the box if it was to move, and was able to find the velocity of the box if it were to move.
