A disk with a diameter of 0.08 m is spinning with a constant velocity about an axle perpendicular to the disk and running through its center.

At this same frequency, what is the period of rotation of this \"halfway point\"?

T =

How long does it take a point on the edge of the disk to travel 1 km?

T1000 =

Suppose we double the diameter of the disk. We still want the same 14 g acceleration at the outer edge. Let f2 be the number of revolutions per second needed to get that acceleration. What is the ratio R = f2/f, where f is your answer to part (a)? Answer according to the following key:

  • 1 = 0.500
  • 2 = 0.707
  • 3 = 1.000
  • 4 = 1.414
  • 5 = 2.000
  • 6 = none of the above

R =

    A solid disk with mass M (1.00 kg) and radius R (0.200 m) is sitting on a frictionless surface. We analyzed the situation at left below, where a force F (2.00 N) is applied for four seconds, by a string that has been wrapped around the outer surface of a cylindrical disk. Two students are debating the following question. ‘The same force is applied for the same amount of time, but this time by a string attached to the edge...
