###### Problem Details

On a farm, you are pushing on a stubborn pig with a constant horizontal force with magnitude 30.7 N and direction 37.0 counterclockwise from the +x-axis.
(a) How much work does this force do during a displacement of the pig that is  s⃗ = (5.00 m) ?
(b) How much work does this force do during a displacement of the pig that is  s⃗ = –(6.00 m) ?
(c) How much work does this force do during a displacement of the pig that is  s⃗ = –(2.00 m) î +(4.00 m) ĵ ?
