Question:

A man slides down on a slide when it is inclined at 32o. What is the coefficient of friction between the man and the slide?

Solution:

$$f = \mu N = \mu m g \cos \theta ;$$ $$f = m g \sin \theta ;$$ $$\mu m g \cos \theta = m g \sin \theta \Rightarrow \mu = \frac {\sin \theta}{\cos \theta} = \tan \theta = 0.625;$$

Answer: $\mu = 0.625$.
