An airplane flies at 150 km/hr. The airplane is towing a bynner that is b=0.8 m tall and =25 m long. If the drag coefficient basec on area b is C=0.06, estimate the power required to tow the banner. For comparison, determine the power required if the airplane was instead able to tow a rigid flat plate of the sande size. Explain why one had a larger power requirement (and larger drag) than the other. Finally, determine the power required if the airplane was towing a smooth spherical balloon with a diameter of 2 m.
