centripetal accel -- airplane flying in a horizontal circle...
An airplane is flying in a horizontal circle at a speed of 116 m/s. The 77.0 kg pilot does not want his centripetal acceleration to exceed 6.00 times free-fall acceleration.
(a) What is the minimum radius of the circular path? (in meters)
(b) At this radius, what is the net force that maintains circular motion exerted on the pilot by the seat belts, the friction between him and the seat, and so forth?
i'm more concentrated on part A.
this is what i have so far:
F=ma=m(v^2/R)=mG
v=116m/s
G=6
so then v^2/R=6, 116^2/R=6
so then
R=2242.7
it says my answer is incorrect.
i don't see my mistake though.
and for part B, would it be 0?
PART A: SOLVED. but i still need help with part B.
Fnet=ma, but i don't think that one works in this case...
