A bowling ball has a mass of 7 kg, a moment of inertia of 2.8 x 10^-2 kgm^2, and a radius of 0.10 m. If it rolls down the lane without slipping at a linear of 4 m/s, what isits total kinetic energy?

Respuesta :

The kinetic energy is given by:

[tex]K=\frac{1}{2}mv^2[/tex]

where m is the mass and v is the velocity; plugging the values given we have that:

[tex]\begin{gathered} K=\frac{1}{2}(7)(4) \\ K=14 \end{gathered}[/tex]

Therefore the kinetic energy of the ball is 14 J
