Coefficient of static friction
Not what you're looking for?
Force of static friction between any two surfaces is given by: Ff=Us*N
How do you find the mass of the coin(m), gravity(g) (9.8m/sec2) and the angle (30) the flat surface makes with the table; Ff=m.g.sin0 and N=m.g.cos0
using the above expressions of Ff and N and the definition of the force of static fricition,show that the coefficient of static friction: Us=tan0=?
