1 answer
The correct answer is:
a. Two people pulling on the same side of a wheelbarrow.
In this situation, the forces are unbalanced because both people are applying force in the same direction, which will cause the wheelbarrow to accelerate in that direction.
Options b and c describe balanced forces, as they involve equal opposing forces. Option d also describes a situation where no force is being applied to the crate, resulting in no movement.
