Find the total work done in moving an object along C if the motion is caused by the force field F. Suppose the arc is measured in meters and the force in Newtons. (x, y, z) = (xy-z) i + yj + zk; C: the line segment from the point of origin, to the point (4, 1, 2).

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
