A box is being pushed across a rough surface and is traveling at a constant speed . What must be true?

It is incurring static friction

Kinetic friction is greater than applied force

Applied force is greater than kinetic friction

A box is being pushed to the right across a flat rough surface by an applied force. If the box is moving with a constant speed , what must be true of the frictional force and the applied force?

Frictional force is EQUAL than the applied force

Frictional force is GREATER than the applied force

Frictional force is LESSER than the applied force
