(8%) Problem 7: Jeremy is playing with a yoyo of mass mo = 34.5 g. The yoyo string is let out to length 7, = 46.1 cm, and he swings the yoyo in a horizontal circle at a constant rate of wp = 5.87 rad/sec. The yoyo string makes an angle of ; with the horizontal, as shown in the figure. Otheexpertta.com 17% Part (a) Choose the correct free body diagram for this problem, where the weight of the yoyo is Wy, the tension in the string is T, and the centripetal force on the yoyo is F.. v Correct! $ 17% Part (b) Calculate the tension, in newtons, of the string. T, =0.05491 N X Incorrect! Feedback: is available. $ 17% Part (c) Calculate the angle, in degrees, between the string and the horizontal. 0, =45.00 X Incorrect! & 17% Part (d) Jeremy increases the angular speed of the yoyo such that the angle decreases to one half of its previous value. Calculate the new angular velocity, in radians per second, of the yoyo. wy = |l rad/s sin() cos() tan() cotan() acos() atan() sinh() cosh() tanh() cotanh() Degrees O Radians Submit Hint Hints: deduction per hint.
