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

Thank you! Just had this explained to me...love this site and thanks for your helpful replies

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
