(11%) Problem 7: Consider the yo-yo (of mass M and outer radius R) shown in the figure, where the string is being pulled with a force of magnitude F (F < M g) at an angle to the horizontal. The radius of the inner axis is r (so that r < R). Assume that the angle ranges from 0 to 7/2, and the coefficient of static friction with the ground is very large. O F Otheexpertta.com 33% Part (a) In what direction will the yo-yo roll? 33% Part (b) Enter an expression for the critical angle (in radians, between 0 and л / 2) at which the yo-yo will remain motionless. Use y = r / R to simplify your expression. 0c = cos(0)¹ y X Attempts Remain 33% Part (c) Calculate this critical angle c, in degrees, if the yo-yo has an outer radius of 3.1 cm and an inner radius of 0.82 cm.
