  1. Convert 16.0 radians to: (a) Revolutions. (b) Degrees.
  2. If a rotating object has a constant angular velocity of 8. 17 rad s , how many revolutions does it make in one minute? (One way to answer this is to convert units, from rad s to (^) minrev .)
  1. A wheel starts rotating from rest and undergoes a constant angular acceleration. (a) In 10 .0 s it makes 75.0 revolutions. What is the angular acceleration of the wheel? (b) What was the angular velocity at the end of the 10.0 s?
  2. An object is rotating at a rate of 130 rad s. It undergoes a constant angular deceleration and comes to rest in 12.0 s. What is the magnitude of the angular acceleration of the object? How many turns did it make in coming to a halt?

  1. Three forces are exerted on a rotating object at the distances and in the directions shown. What is the total torque on the object? (Take “counter-clockwise” to be the positive sense of ro- tation.)

  1. A 300-N sign is suspended from a horizontal 4.00-meter long uniform 100-N rod as indicated at the right. The sign is attached to the rod at a point which is 3.0 m from the wall; The left end of the rod is pivoted and the right end is supported by a thin cable making a 30. 0 ◦^ angle with the vertical. Find the tension T in the cable.
