Question: A box of mass 12.5 kg rests on the flat bed of a truck; the box is not tied down in any way. The coefficients of friction between the box and the flat bed are µs = 0.18 and µk = 0.16. The truck stops at a stop sign and then starts to move to the West with a carelessly large acceleration of 2.25 m/s+.
Part A: While the truck is accelerating westward at 2.25 m/s2, what will be the magnitude of the acceleration of the box?
I need help to find the magnitude of the acceleration of the box.
