Question

A 54-kg jogger is running at a rate of 3 m/s. What is the kinetic energy of the jogger? A. 18 J B. 81 J C. 162 J D. 243 J

Answer 1

The answer would be be D.243 j

Explanation:

Answer 2

`\displaystyle\bf\\\text{\bf kinetic energy}=(mv^2)/(2)=(54*3^2)/(2)=27*9=\boxed{\bf243~J} \\\\\text{\bf Correct answer: D.}`
