QUESTION 3

  1. An electric fan is turned off, and it slows down from 356 revolutions/s to 80.1 revolutions/s in 4.07 seconds. How many times did the fan blades spin in this time?

QUESTION 4

  1. A disk rotates about a fixed axis through its center of mass and perpendicular to the disk. It starts from rest and accelerates uniformly, reaching angular speed ω after 8.44 revolutions. If it continues to accelerated at the same rate, how many more revolutions would it take the disk to reach angular speed 9.35ω rad/s?
