Question #637

Helicopters rotor blades could spin at high speed of 400 rpm. Find the angular displacement in radians for 7 hours operation.

Answer

The rotor blades spin at 400 revolutions per minute. So, in seven hours, the blades perform  revolutions.


Since one revolution is  radians, we can deduce the angular displacement of the blades :  radians.
