Transcribed Image Text:**Problem:**
2. A wheel spins rather slowly at first, taking 8 seconds for every spin. It then accelerates at \(\frac{\pi}{3} \, \text{rad/s}^2\). How long does it take for the wheel to make 2 complete turns?
Fill in the table with what is given and what is needed. All values in the table should be in terms of radians. Hint: the answer is not 8 or 16.
**Table:**
| \(\Delta \theta\) | |
|-------------------|-----------|
| \(\omega_i\) | |
| \(\omega_f\) | |
| \(\alpha\) | |
| \(\Delta t\) | |
**Explanation:**
- \(\Delta \theta\) represents the angular displacement.
- \(\omega_i\) is the initial angular velocity.
- \(\omega_f\) is the final angular velocity.
- \(\alpha\) is the angular acceleration.
- \(\Delta t\) is the time taken.
The problem asks you to determine the time \(\Delta t\) for the wheel to complete 2 full turns with the given acceleration. Fill in the table with values in radians based on the information provided.
