Question

What is the speed of a 84.3 kg woman running with kinetic energy of 1457 j

Answer 1

The answer is 5.88 m/s

Step-by-step explanation:

The speed of the woman can be found by using the formula

`v = \sqrt{ (2KE)/(m) } \\`

m is the mass

From the question we have

`v = \sqrt{ (2 * 1457)/(84.3) } = \sqrt{ (2914)/(84.3) } \\ = 5.879372...`

We have the final answer as

5.88 m/s

Hope this helps you
