An airplane is flying in a horizontal circle at a speed of 104 m/s. the 85.0 kg pilot does not want the centripetal acceleration to exceed 6.35 times free-fall acceleration.
(a) find the minimum radius of the plane’s path.
(b) at this radius, what is the magnitude of the net force that maintains circular motion exerted on the pilot by the seat belts, the friction against the seat, and so forth?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

=force × distance a. work b. velocity c. pressure d. momentum
