Question

consider a box sitting in the back of a pickup. the pickup accelerates to the right, and because the bed of the pickup is sticky, the box does not slide around the truck when this happens.

Answer 1

The pickup accelerates towards right. The box is sticky to the pickup, thus its acceleration is the same, towards right. Its inertia (force) is oposing the acceleration, thus it is towards left. For the box not to move, it is necessary that the truck acts on it with a force towards right. (The two forces of the truck on box and the box inertia (force) equilibrate themselves).
