Rotational Speed

  1. Given an object, of radius 0.25m, rotating at 6400 RPM calculate and .
  2. Given an object, of radius 0.35m, rotating at 9600 RPM calculate and .

Angular Velocity – Pt. 1

  1. Given a rotation through an arc length of 1.25m, with a radius of rotation to be 0.75m. After 2 seconds calculate Δθ (radians and degrees), ω (rad/s), and VT (m/s).
  2. Given a rotation through an arc length of 0.45m, with a radius of rotation to be 1.75m. After 0.5 seconds calculate Δθ (radians and degrees), ω (rad/s), and VT (m/s).

Angular Velocity – Pt. 2

  1. Given ω=2.6 m/s calculate the tangential velocities (m/s) of two objects one at a radius of 0.25m and the other at 0.85m.
  2. Given ω=5.4 m/s calculate the tangential velocities (m/s) of two objects one at a radius of 1.25m and the other at 2.85m.
