Ajet pilot takes his aircraft into a vertical loop. if the jet is moving at a speed of 700km/hr at the lowest point in the loop, determine the radius of the circle so that the acceleration which the pilot experiences at the lowest point of the loop does not exceed 6 time the acceleration due to gravity or (6g’s).
