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}

(b)

16\,\text{rad}

(c)

8.0\,\text{rad}

(d)

3.2\,\text{rad}
