Answer to Question #84879 in Mechanics | Relativity for Diana

Question

If I have coefficient of friction and degree of incline and distance traveled, how do I figure acceleration?

Answer 1

From the Newton's second law:

$$Ox: ma=mg\text{sin}\theta-kN,$$ $$Oy: mg\text{cos}\theta=N,$$

it gives

$$a=g(\text{sin}\theta-k\cdot\text{cos}\theta).$$

This expression does not imply having distance traveled, the coefficient of friction and degree of incline will be enough.
