Question

kyle has a mass of 54 kg and is jogging at a velocity of 3 m/s. what is kyles kinetic energy? (formula: ke = 1/2mv²) 243 j 18 j 162 j 81 j

Explanation:

Step1: Identify the formula

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

Step2: Substitute the given values

Given $m = 54$ kg and $v=3$ m/s. Substitute into the formula: $KE=\frac{1}{2}\times54\times3^{2}$.

Step3: Calculate the value

First, calculate $3^{2}=9$. Then, $\frac{1}{2}\times54\times9 = 27\times9=243$ J.

Answer:

243 J
