Final answer:
The angular acceleration of the tires is 1.0 m/s².
Step-by-step explanation:
To find the angular acceleration of the tires, we need to use the formula:
angular acceleration = (final angular velocity - initial angular velocity) / time
Given that the boy on the bicycle accelerates from rest to a speed of 10.0 m/s in 10.0 s, we can calculate the angular acceleration as:
angular acceleration = (10.0 m/s - 0 m/s) / 10.0 s = 1.0 m/s²
Therefore, the angular acceleration of the tires is 1.0 m/s².
