for part a: How is it 6.1 x10^6 every time I do the calculation I get 6.1 x10^4. Can you offer me some explanation/help understanding please?

Hi klgully,

Are you remembering to square the $\dfrac{1}{100}$ factor in the denominator? That would put your answer off by a factor of 100.

Cheers,
Mr. Dychko

You're welcome, and thanks for the very nice feedback!

Why is it 1/2 of m*g

Hello, thanks for the question. The lady has two heels, so the weight supported by one heel is half the lady's weight, which works out to $\dfrac{1}{2}mg$.

Cheers,
Mr. Dychko
