A block of weight \( 100 \mathrm{~N} \) is slowly slid up on a smooth incline of inclination \( 37^{\circ} \) by a person. Calculate the work done by the person in moving the block through a distance of \( 2.0 \mathrm{~m} \), if the driving force is (a) parallel to the incline and (b) in the horizontal direction.
