A golf ball of diameter 1.69 inches can travel at a velocity of 200 ft/s as it leaves the tee. Determine the drag force FD on a golf ball assuming it is a smooth sphere. (Assume the air is at 60 F and standard pressure.) Now determine the drag force on an actual golf ball assuming CD = 0.25. How do the two forces compare?
note: this is the last question I have posted out of 6, please help me out because this is my last homework for the semester and I am studying for a final exam. thank you so much in advance.
