A bowling ball with a mass of 8 kg is moving at a speed of 5 m/s. What is itskinetic energy?O A. 40 JO B. 20 JO C. 2003 JO D. 100 J

Respuesta :

Given:

The mass of the bowling ball is m = 8 kg

The speed of the ball is v = 5 m/s

To find the kinetic energy.

Explanation:

The kinetic energy can be calculated by the formula

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

On substituting the values, the kinetic energy will be

[tex]\begin{gathered} K.E.\text{ = }\frac{1}{2}\times8\times(5)^2 \\ =\text{ 100 J} \end{gathered}[/tex]

Thus, the kinetic energy is 100 J.
