Problem

A solid wheel of radius

0.40\,\text{m}

starts from rest and rolls without slipping along a horizontal surface. After

2.0\,\text{s}

its center has traveled

3.2\,\text{m}

. Assuming the wheel’s angular acceleration is constant, what is its angular displacement during this interval? a)

4.0\,\text{rad}

16\,\text{rad}

8.0\,\text{rad}

3.2\,\text{rad}
