Homework Statement
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"
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?
Homework 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
