- Homework Statement
- The 7.80 kg spool has a radius of gyration of 0.320 m and rolls without the ropes slipping. The ropes have negligible mass.

There is also a force pulling the spool upward at 100N and the outer radius is 0.5 and the inner radius is 0.2-shown in picture

Let up be the positive y-direction and CCW be the positive rotational direction.

Assume 3 SF for all givens.

- Relevant Equations
- Torque = I*a

Io=m*ro^2

What I did was plug in the outer radius time the force into the torque and then the mass moment of inertia is equal to m*ro^2 so then I plugged in the mass times the radius of gyration squared into I and solved for a but this is not right.
