(7%) Problem 7: Jeremy is playing with a yoyo of mass mo = 25.9 g. The yoyo string is let out to length r, = 56.6 cm, and he swings the yoyo in a horizontal circle at a constant rate of wo = 5.12 rad/sec. The yoyo string makes an angle of 0, with the horizontal, as shown in the figure. Wo T 17 % Part (a) Choose the correct free body diagram for this problem, where the weight of the yoyo is Wo, the tension in the string is T,, and the centripetal force on the yoyo is Fe.

Calculate the new angular velocity, in radians per second, of the yoyo. 17% Part (e) In Part (d), Jeremy increased the angular speed of the yoyo such that the angle decreased to one half of its initial value. Calculate the new tension, in newtons, of the string using consistent with Part (d). 17% Part (f) If the increase in the angular velocity of the yoyo took place over 1.2 seconds, calculate the angular acceleration o, in radians per square second, of the yoyo during the increase.
