A yoyo with a mass of m = 153 g is released from rest as shown in the figure.
The inner radius of the yoyo is r = 2.77 cm, and the outer radius is R = 4.49 cm, and the moment of inertia about the axis perpendicular to the plane of the yoyo and passing through the center of mass is ICM = 1.28 x 10-4 kgm2. Determine the linear acceleration of the yoyo.
Determine the angular acceleration of the yoyo.
What is the weight of the yoyo?
What is the tension in the rope?
If a 1.66 m long section of the rope unwinds from the yoyo, then what will be the angular speed of the yoyo?
