A bowling ball has a mass of 3.7kg, a moment of inertia of 0.340992kg*m^2, and a radius of 0.48m. It rolls along the lane withou

Kinetic energy due to linear motion:

$E= \frac{1}{2}mv^2= \frac{1}{2}3.7(3.2)^2=18.944J$

The angular velocity is found by

$v=r \omega$

$\omega = \frac{v}{r}= \frac{3.2}{0.48} =6.667rad/s$

Kinetic energy due to rotational motion:

$E= \frac{1}{2}I \omega^2 = \frac{1}{2}0.340992(6.667)^2=7.5776J$
Then
$E_{total}=18.944J+ 7.5776J=26.5216J$
