An object of mass \( m \) is connected to a trailer by a rope. What will happen if the tractor starts pulling the trailer?

A. The trailer moves with uniform velocity.
B. The object experiences a force.
C. The trailer moves freely without any resistance.

Answer :

Final answer:

The trailer experiences a force when the tractor starts pulling it, which leads to its acceleration and an increase in kinetic energy if frictional forces are negligible.

Explanation:

When a tractor starts pulling a trailer connected by a rope, the trailer will experience a force due to the tractor's pull. This force will lead to an acceleration of the trailer, increasing its kinetic energy, provided that the frictional forces are negligible. The work done by the tractor on the trailer can be calculated with the equation W = Fd, where W is the work, F is the force exerted by the tractor, and d is the distance over which the force is applied, similar to the calculation found for potential energy due to gravity. The correct answer to the student's question is that the object, in this case, the trailer, experiences a force as the tractor pulls it.
