Pilot Blackout in a Power Dive.? A jet plane comes in for a downward dive as shown in Fig. The bottom part of the path is a quarter circle with a radius of curvature of 350 m. According to medical tests, pilots lose consciousness al an acceleration of 5.5?g?. At what speed (in m/s and in mph) will the pilot black out for this dive? Figure:

Solution 27E Step 1: Here, we can use the equations for centripetal motion since, the aeroplane is experiencing a centripetal force. In circular motion, the equation for centripetal acceleration, a = v /r 2 Where, v- velocity of the object r - radius of the circular path
