Question

A small blimp is used for advertising purposes at a football game. It has a mass of 93.0 kg and is attached by a towrope to a truck on the ground. The towrope makes an angle of 53.3° downward from the horizontal, and the blimp hovers at a constant height of 20.7 m above the ground. The truck moves on a straight line for 783.4 m on the level surface of the stadium parking lot at a constant velocity of 9.0 m/s. If the drag coefficient (K in
F = Kv2)
is 0.5 kg/m, how much work is done by the truck in pulling the blimp (assuming there is no wind)?
