I filled out the experiment data as shown, but how do i go about finding the F of N, f, and the mu of s? Please explain by showing the formulas?
The actual experiment: We put a marble block on a wooden plank, and lifted the plank higher and higher until the block slid down, recording the angle of the breaking point (recorded in the table). We found the mass of the block, also shown.
