>
Constants
A jet pilot takes his aircraft in a vertical loop, as shown in
the figure(Figure 1).
If the jet is moving at a speed of 840 km/h at the lowest point of the loop, determine the minimum radius of the
circle so that the centripetal acceleration at the lowest point does not exceed 6.3 g's.
Express your answer to two significant figures and include the appropriate units.
r = 880 m
