with free body diagram

1. (5) A constant force $\vec{F}=(2.0\widehat{?}+4.0\widehat{?})\mathrm{N}$ acts on an object as it moves along a straight-line path. If the object's displacement is $\vec{d}=(1.0\widehat{?}+5.0\widehat{?})\mathrm{m}$, calculate the work done by force $\vec{F}$. 2. (5) A tow rope pulls a water skier with constant velocity for a distance of $65\mathrm{m}$ before the skier falls. The tension in the rope is $100\mathrm{N}$, and the rope makes an angle of $?=34^{?}$ with respect to the direction the boat travels. Calculate the work done by the rope on the skier.
