A 78.4-kg airplane pilot pulls out of a dive by following, at a constant speed of 162 km/h, the arc of a circle whose radius is 321.0 m. At the bottom of the circle, he is accelerating at 6.31 m/s upwards. What is the force exerted on the pilot by the airplane seat?
Fnet = ma ...?
The Attempt at a Solution
I found the net force acting on him at the bottom of the circle, which is 494.7N...but I don't know how this relates to the force I'm looking for?
