On a farm, you are pushing on a stubborn pig with a con- stant horizontal force with magnitude 30.0 N and direction 37.0° counterclockwise from the +x-axis. How much work does this force do during a displacement of the pig that is (a) s S = 15.00 m2nd; (b) s S = −16.00 m2ne; (c) s S = −12.00 m2nd + 14.00 m2ne?
