The propeller of a World War II fighter plane is 2.79 m in diameter. (a) What is its angular velocity in radians per second if it spins at 1300 rev/min? rad/s (b) What is the linear speed (in m/s) of its tip at this angular velocity if the plane is stationary on the tarmac? m/s (c) What is the centripetal acceleration of the propeller tip under these conditions? Calculate it in meters per second squared and convert to multiples of g. centripetal acceleration in m/s2 m/s2 centripetal acceleration in g Additional Materials Reading Submit Answer Practice Another Version +-14 points OSColPhysAP2016 6.2.P.016. BM Olympic ice skaters are able to spin at about 2 rev/s. (a) What is their angular velocity in radians per second? rad/s (b) What is the centripetal acceleration in m/s) of the skater's nose if it is 0.115 m from the axis of rotation? m/s2 (c) An exceptional skater named Dick Button was able to spin much faster in the 1950s than anyone since-at about 9 rev/s. What was the centripetal acceleration (in m/s2) of the tip of his nose, assuming it is at 0.115 m radius? m/s2 (d) Comment on the magnitudes of the accelerations found. It is reputed that Button ruptured small blood vessels during his spins.
