A string is wrapped around a pulley of radius 3.45cm , and a weight hangs from the other end. The weight falls with a constant acceleration 3.00m/s2 .
What's the angular acceleration of the pulley?
i'm writing out the equations i would think that are involved.
Centripital force Fr=mv^2/R ( i think)
Newtons second law
The Attempt at a Solution
I am just so stuck...and don't know how to start.
I drew out a free body diagram and Drew out the forces for the mass and pulley
For the mass all i have is the Tension and mg. there is no weight for the pully so all i have is tension
I would need to sum the forces right?
