    A child pulls a block across the floor with force applied by a horizontally held string. A smaller frictional force also acts upon the block yielding a net force on the block that is smaller than the force applied by the string. How does the work done by the string compare with the change in the block’s kinetic energy? the work done is greater than the change in the kinetic energy of the block The work done is equal to...
