Example 7.1 Whirlybirds Goal Convert an angular speed in revolutions per minute to radians per second. Problem The rotor on a helicopter turns at an angular speed of 3.40 x 102 revolutions per minute. Express the angular speed in radians per second. Strategy During one revolution, the rotor turns through an angle of 27 radians. Use this relationship as a conversion factor. Solution Apply the conversion factors 1 rev = 2r and 60 S = 1 min. = 3.40 x...

The flywheel of a steam engine runs with a constant angular speed of 416 rev/min (in the counterclockwise direction). When the steam is shut off, the friction of the bearings stops the wheel in 2.1 h. (HINT: Be careful with the units.) (a) What is the magnitude of the constant angular acceleration, in revolutions per minute-squared, of the wheel during the slowdown? (b) How many revolutions does the wheel make before stopping? (c) At the instant the flywheel is turning...
