an atwoods machine has a solid cylindrical pulley with a mass of 200g and a radius of 10cm. a 1.2 kg mass is hung on one side and a 1.1kg mass on the other side, find the acceleration of the two masses and the itme for them to travel a distance of 60cm

Answer 1

Model the pulley as a solid disk, and get the moment of inertia for that model.

(1.2kg-1.1kg)g= 1.2kg*a+1.1kg*a+ I*a/r

solve for a
