select the correct answer. jim has a mass of 15 kilograms and is running on the ground with a velocity of…

Explanation:

Step1: Recall kinetic - energy formula

The formula for kinetic energy is $K.E.=\frac{1}{2}mv^{2}$, where $m$ is the mass and $v$ is the velocity.

Step2: Substitute given values

Given $m = 15$ kg and $v=2.7$ m/s. Substitute into the formula: $K.E.=\frac{1}{2}\times15\times(2.7)^{2}$. First, calculate $(2.7)^{2}=7.29$. Then, $\frac{1}{2}\times15\times7.29 = 7.5\times7.29=54.675\approx55$ J.

Answer:

B. 55 joules
