A plane is in a dive. At the bottom of the dive is the maximum acceleration on the pilot. This part of the dive can be approximated by a circular path. If the centripetal acceleration on the pilot is 8.90 times g (=9.81 m/s2), what is the force felt by the pilot if her mass is 56.0 kg. If the speed of the plane is 345 km/h, what is the radius of the circular path?
