If you drag a sled across the ground, the sled experiences what kind of friction?

A. Kinetic friction

B. rolling friction

C. static friction

D. cohesive friction

A. kinetic friction

Answer: The correct answer is option A.

Explanation:

Kinetic friction is defined as the frictional force acting between the two objects in contact. It resists the motion of one object over the other.

Rolling friction is defined as the frictional force which acts on the rolling object.

Static friction is the frictional force that keeps an object at rest.

Cohesive friction is defined as the frictional force that hold the particles together.

We need to drag a sled across the ground, so the frictional force is acting between two objects. Here, one object is sled and other is the ground. So, in order to move the sled, it must overcome kinetic friction.

Hence, the correct option is A.
