The pilot of a jet fighter will black out at an acceleration greater than approximately a1 = 5.00 g if it lasts for more than a few seconds. Express a1 in m/s2. Express a1 in ft/s2. The acceleration of the passenger during a car crash with an air bag is about a2 = 65.0 g for a very short time. What is a2 in m/s2? What is a2 in ft/s2?

When a fighter pilot makes a very quick turn, he experiences a centripetal acceleration. When this acceleration Is greater than about 4 times g the pilot will usually lose consciousness ("black out"). Consider a pilot flying at a speed of 800 m/s who wants to make a very sharp turn. What is the minimum radius of curvature that he can take without blacking out?

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.
