A yoyo with a mass of m = 179 g is released from rest as shown in the figure.

https://s6.lite.msu.edu/res/msu/nagytibo/Mechanics/Rotation/Graphics/001a.gif" [Broken]

The inner radius of the yoyo is r = 2.60 cm, and the outer radius is R = 3.60 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 = 9.70×10-5 kgm2.

1.Determine the linear acceleration of the yoyo.

2. Determine the angular acceleration of the yoyo.

3.What is the weight of the yoyo?

4.What is the tension in the rope?

5.If a 1.04 m long section of the rope unwinds from the yoyo, then what will be the angular speed of the yoyo?

2. Relevant equations

These are the equations I believe to be correct. However, they are not working out.

1) a = g*[1 - I/(mr²+I)]

2) α = a/r

3) W = m*g

4) T = g*I*m/(mr²+I)

5) w = v/r = √(2ay)/r

3. The attempt at a solution
