 P: 86 1. The problem statement, all variables and given/known data As a pilot comes out of a dive in a circular arc she experiences an upward acceleration of 9.0 gs (i.e. 9 x 9.8). a) Mentions that the Pilot's mass is 60 kg, already solved this b) If the speed of the plane is 330 km/h, what is the radius of the plane's arc? 2. Relevant equations ac = v2/r Fnet = $$\Sigma$$F 3. The attempt at a solution No idea what to do because I can't figure out what is causing the centripetal acceleration. mv2/r = - mg I don't know the mass of the plane, and if I add another force which I assume would cause the centripetal acceleration then I have no way of calculating that either.
 HW Helper P: 6,214 The upward acceleration the pilot experiences is directed towards the center of rotation, so you are given the centripetal acceleration.
