A 70 kg stunt pilot begins pulling out of a dive into a vertical circle. If the plane’s speed at the lowest point of the circle is 80 m/s, what is the apparent weight of the pilot at the lowest point of the pullout? The pilot experiences a force of 5g from the centripetal acceleration at the bottom of the dive.
