Question $7\mathrm{.}25-$ Asphalt pavement roller ${?}^8$ here has a mass of $10,000kg.$

Its wheels have a radius of gyration of $0\mathrm{.}5$ m and a mass of $2,000kg$

each. The diameter of each wheel is $1\mathrm{.}1$ m $.$ If the roller is moving at a

speed of $10k\frac{m}{h},$ its kinetic energy $(N-m)$ is most nearly:

A$.15,000$

B$.30,000$

C$.40,000$

D$.70,000$Question $7\mathrm{.}25-$ Asphalt pavement roller ${?}^8$ here has a mass of $10,000kg.$
