A collie drags its bed box across a floor by applying

A collie drags its bed box across a floor by applying a horizontal force of 8.4 N. The kinetic frictional force acting on the box has magnitude 1.9 N. As the box is dragged through 0.35 m along the way, what are (a) the work done by the collie's applied force and (b) the increase in thermal energy of the bed and floor? (a) Number Units (b) Number Units
