Practice covered

  1. A circle is spinning at 1 radian per second. Approximately how long does it take to complete one full rotation?
  2. An object starts from rest with a constant angular acceleration of alpha = 3 rad/s^2. What is its angular velocity omega (in rad/s) after 4 seconds?
  3. An object starts from rest (omega_i = 0) with angular acceleration alpha = 2 rad/s^2 and rotates through one complete revolution. What is omega_f (in rad/s)? Round to two decimal places.
  4. A point on a rotating platform is located at distance r from the center. If the platform rotates with angular velocity omega, what is the tangential speed of the point?
  5. A point on a rotating disk experiences both tangential and centripetal acceleration. These two acceleration components are:
  6. A point on a disk is located 0.5 m from the center. The disk has angular acceleration alpha = 4 rad/s^2 and angular velocity omega = 6 rad/s. What is the magnitude of the total acceleration (in m/s^2)?
