- 1)Find the acceleration of the hanging block
2)Assuming the system starts at rest, Find the velocity of the block when Pulley 2 completes 2 full revolutions
- Relevant Equations
- Σ F= ma
Σ τ= Iα
For point one I analyzed all of the forces, called the tension on the right and the left one , and taking as positive the clock-wise and upwards directions I found:
I solved the system and found that thus I have that which doesn't make sense, where did I make the mistake?
The only thing that raises my suspicion are the angular accelerations, Because I considered I don't know If it is a fair assumption to make.
As for point two genuinely don't know how to do it. I suppose that I would have to use the energetic balance, since the system is conservative. Yet I don't know how to translate into math the 2 revolutions of pulley 2.
