What does a sled experience if it is dragged across the ground? A. kinetic friction B. static friction C. rolling friction D. cohesive friction

A. kinetic friction.

Explanation:

Kinetic friction is the friction which occurs between the surfaces of the two object while one object is moving with respect to other or both moving with respect to each other. Rolling friction is the friction force which occurs while rolling of object. Static friction is the friction which is required to keep the object in rest. Cohesive friction is the frictional force which is required to hold the particles.

While dragging a sled over the ground there will be occurrence of frictional force which is applies between two objects. Here, one object is ground and other is the sled. So, in order to move the sled over the ground, it must overcome the force of kinetic friction.

My guess it A. Kinetic friction because it is moving and kinetic energy generates in a moving object
