Question: 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,

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. Does the work done by the force applied by the string equal the change in kinetic energy in this situation? Explain.
