A skydiver has a mass of 61 kg. Suppose that the air resistive
force acting on the diver increases in direct proportion to his
velocity such that for every 10 m/s that the diver’s velocity
increases, the force of air resistance increases by 104 N.
Use g = 9.8 m/s^2. Let F1 be the net force
acting on the skydiver when his velocity is 46. Let a1
be the acceleration of the skydiver at that moment. Let
vT be the terminal velocity of the skydiver. Compute
F1+2*a1+3*vT.
