Answer:
0.36 m
Explanation:
The moment of inertial of a wheel can be calculated as
[tex]I=mr^2[/tex]Where r is the radius of the wheel and m is its mass.
Solving the equation for r, we get
[tex]r=\sqrt[]{\frac{I}{m}}[/tex]So, replacing I by 0.13 kg m2 and m by 0.98 kg, we get
[tex]r=\sqrt[]{\frac{0.13\operatorname{kg}\cdot m^2}{0.98\operatorname{kg}}}=0.36\text{ m}[/tex]Therefore, the radius of the wheel is 0.36 m
