2013 Indianapolis 500 champion Tony Kanaan holds his hand out of his IndyCar while driving through still air with standard atmospheric conditions.

(a) For safety, the pit lane speed limit is \(60 \mathrm{mph}\). At this speed, what is the maximum pressure on his hand?

(b) Back on the race track, what is the maximum pressure when he is driving his IndyCar at \(225 \mathrm{mph}\) ?

(c) On the straightaways, the IndyCar reaches speeds in excess of \(235 \mathrm{mph}\). For this speed, is your solution method for parts (a) and (b) reasonable? Explain.
