A steel beam is rotated in a horizontal plane to provide the centripetal acceleration for
training pilots. If the pilot sits 2.0 m from the center of rotation, at what speed must he rotate
to experience a horizontal centripetal acceleration of 78 m/s??

Respuesta :

MathPhys

Answer:

12 m/s

Explanation:

a = v² / r

78 m/s² = v² / 2.0 m

v = 12.49 m/s

Rounding to two significant figures, the speed is 12 m/s.
