Question

A fan blade is rotating with a constant angular acceleration of +12.8 rad/s2. At what point on the blade, as measured from the axis of rotation, does the magnitude of the tangential acceleration equal that of the acceleration due to gravity? (g = 9.80 m/s2)

Answer 1

Answer:

At r= 0.76 m measured from the axis of rotation, does the tangential acceleration equals the acceleration of the gravity.

Explanation:

at=g= 9.8 m/s²

α= 12.8 rad/s²

r= at/α

r= 0.76m
