Take a look at the textbook, Ch. 12, problem #70. Except, change
the location of the center of mass to 9.7 cm from the eraser and
change the distance of the center of mass from the pencil's lead
tip to be 11 cm. Finally, assume that the coefficient of friction
is 0.7. Now solve for the minimum angle such that the pencil won't
slip. Enter your answer in degrees.
