1. The problem statement, all variables and given/known data A 65 kg airplane pilot pulls out of a dive by following at constant speed, the arc of a circle whose radius is 300 m. At the bottom of the circle her speed is 180 km/h. a.) Calculate net force on pilot at bottom or circle. b.) Calculate force exerted on pilot by seat at top and bottom of circle. c.)Calculate minimum speed required so pilot doesn't fall out at top of circle if she's not wearing a seatbelt. 2. Relevant equations Newton's second law, a=v^2/r 3. The attempt at a solution For part a) the only two forces I could think of are the normal and weight down. So net force would be zero since they cancel each other out? For part b) at top: n+mg=(v^2/r)m, plugging in numbers I get -95.3 N. For the bottom n-mg=(v^2/r)m, and I got 1179 N. For part c.) n would = 0, so mg=(v^2/r)m, and plugging in numbers I get 54.22 m/s^2. I'm not sure if I did part a) right, but I feel pretty confident about the other parts, did I go about doing those parts correctly?
