Worked practice questions

A wheel starting from rest reaches 20 rad/s in 4 s. Angular acceleration alpha:

  1. 2 rad/s²
  2. 80 rad/s²
  3. 1 rad/s²
  4. 5 rad/s²
Show answer and solution

Correct answer: D. 5 rad/s²

We have alpha = (omega - omega0)/t. That is alpha = (20 - 0)/4. So alpha = 5 rad/s².
