Question:
How do I the radius of curvature of the loop in meters for a plane flying 600m/s experiencing 4g when pulling out of a dive?



Replies:
The acceleration of an object moving in a circular path is v^2/r, where v is the speed and r is the radius.

Tim Mooney


The formula for the centripetal acceleration is a = v^2/r, where v is the tangential velocity and r is the radius of curvature. In your case, a = 3g (4g - 1g for the earth's gravity) and v = 600 m/s. All you need to do is solve for r.
