Total Number Distance from the Center of Disk (m) Force of Friction (N)
1 0.2 0.6
2 0.5 1.5
3 0.7 2.1

An object rotates at various distances from the center of a disk such that the object experiences a force of friction from the disk. Data collected from the experiment are shown in the table above. Each location of the disk rotates such that the tangential speed at that point remains constant. What is the magnitude of the force of friction exerted on the object if its mass is doubled and it is placed at a distance of 0.6  m from the disk’s center?

  • A- 0.9  N

  • B- 1.8  N

  • C- 3.6  N

  • D- The answer cannot be determined without knowing the original mass of the object.

    An object is placed on top of a horizontally rotating disk at a distance of 0.2 m from the center (axis of rotation). We observe that the object starts sliding when the frequency of the disk’s rotational motion is 30 revolutions/min. Find the coefficient of static friction between the object and the disk. Use g = 10 m/s2.
