Answer:

The answer is 5.88 m/s

Explanation:

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

[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]

m is the mass

From the question we have

[tex]v = \sqrt{ \frac{2 \times 1457}{84.3} } = \sqrt{ \frac{2914}{84.3} } \\ = 5.879372...[/tex]

We have the final answer as

5.88 m/s

Hope this helps you
