Question

On a farm, you are pushing on a stubborn pig with a constant horizontal force with magnitude 33.9 N and direction 37.0 degree counterclockwise from the+ x-axis. How much work does this force do during a displacement of the pig that is s = (5.00 m)i? Express your answer with the appropriate units. How much work does this force do during a displacement of the pig that is s = -(6.00 m)j? Express your answer with the appropriate units. How much work does this force do during a displacement of the pig that is s = -(2.00 m)i + (4.00 m)j? Express your answer with the appropriate units.

Explanation / Answer

force applied by us = (27.12)i + (20.34)j

a. work done by force during 5i displacement = 27.12*5 = 135.60J

b. work done by force during -6j displacement = 20.34*-6 = -122.04J

c. work done by force during -2i + 4j displacement = -2*27.12 + 4*20.34 = 27.12J
