Physics problem involving a jet?

A jet pilot takes his aircraft in a vertical loop


(a) If the jet is moving at a speed of 1900 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 6.0 g's.


____m


(b) Calculate also the 72 kg pilot's effective weight (the force with which the seat pushes up on him) at the bottom of the circle.


____N


(c) Calculate the pilot's effective weight at the top of the circle. (Assume the same speed.)


____N

Physics problem involving a jet?
a) a=V/t V=d/t


V=at d=t/V


Find d. d = t/V/t= t/a/t = t**2/a





V=1900Km/ h X(1000m/Km X 3600sec/h) = 6.84X10**9


a=,.6g= 0.6X.989 Km/sec**2 =593.5m/sec**2





b) F = ma F = weight g = 1+.6g


weight = 72Kg X .593.5m/sec**2 =newtons





c) Weight= MA = 72km X (1-0,6) X V=d/t d=t/Vm/t**2


= 72 km X (,4) X 989.5 m/sec**2
