Question

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

Answer 1

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.

Step-by-step explanation:

The kinetic energy can be calculated by the formula

`K.E.\text{ = }(1)/(2)mv^2`

On substituting the values, the kinetic energy will be

`\begin{gathered} K.E.\text{ = }(1)/(2)*8*(5)^2 \\ =\text{ 100 J} \end{gathered}`

Thus, the kinetic energy is 100 J.
