For example,
To convert 1 inch into cm, firstly we have to know the relation between inch and cm.
Hence, using conversion factor inch is converted into cm.
Answer:
Explanation:
0.2 rev/s = 0.2 rev/s * 2π rad/rev = 0.4π rad/s
Since the angular acceleration is assumed to be constant, and the wheel's angular speed is increasing from rest (0 rad/s) to 0.4π rad/s within 23.8s. Then the angular acceleration must be
