Place a coin at one edge of a textbook and slowly lift the book. When the coin just starts to slip down the incline, measure the angle (theta). Find Ff = m*g*sin(theta) and N = m*g*cos(theta).
Do I need to know the mass of the coin(m), gravity(g), and the angle(theta) the flate surface makes with the table?
