Question

A crate is sitting in the center of a flatbed truck. As the truck accelerates to the east, the crate moves with it, not sliding on the bed of the truck. In what direction is the friction force exerted by the bed of the truck on the crate?

Answer 1

Answer:East

Explanation:

Given

The truck is accelerating towards east along with crate and crate is not sliding.

Friction Force on the crate will act towards the east as friction Force always opposes the motion of an object. Also in this case, if friction force is absent then crate would have moved backward.

Thus static Friction will help the crate to move with truck.
