In order to impress your neighbors and improve your vision in traffic jams, you decide to mount a cylindrical periscope 2.0 m high and 0.1 m in diameter on top of your car. you consult the literature and find that the drag coefficient (based on frontal area) is 1.1 for re< 200,000 (re based on diameter) and drops to 0.35 for re> 200,000. using this information, answer the three questions given. (hint: make a sketch)the periscope's drag at your maximum speed of 75 mph is about: (a) 45 n(b) 4 n(c) 450 n(d) 5 n
