Question

A 45 kg man is running 22 m/s. Calculate the kinetic energy

Answer 1

10890 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass

v is the velocity

From the question we have

`k = (1)/(2) * 45 * {22}^(2) \\ = (1)/(2) * 45 * 484 \\ = 45 * 242 \\ = 10890`

We have the final answer as

10890 J

Hope this helps you
