    A 20,000 kg jet takes off from an aircraft carrier via a catapult. The jet's engines exert a constant force of 136 kN on the jet. The force exerted on the jet by the catapult is plotted in Fig. 7-24b (see attachment) with F1 = 1200 kN and F2 = 73 kN.
    (a) Determine the work done on the jet by its engines during the launch of the jet.
    (b) Determine the work done on the jet by the catapult during the launch of the jet.
