Problem

A box is pushed from point A to point B by the same horizontal force of

40\,\text{N}

. In case I the box is moved directly along the straight line AB, a distance of

6\,\text{m}

. In case II the box is moved along a curved path of length

10\,\text{m}

but still starts at A and ends at B. a. (i) In which case is the work done by the force greater? b. (ii) Give a reason for your answer.
