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?

Part A:

Part B:

Explanation:

Part A:

Airplane is moving in circular path so acceleration in circular path is given by:

Where:

V is the velocity of object in circular path

r is the radius of circular path

In order to find radius r. Above equation will become:

V=104 m/s

a_c=6.35*g=6.35*9.8=62.23 m/s^2

Part B:

Force on a object moving in a circular path is:

r=173.806 m

m=85 kg

V=104 m/s

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

conduction, convection, radiation
