Object 1 rolls up the incline without slipping. Object 2 rolls down the incline without slipping.
Object 1 is a solid sphere and has mass 2kg and radius R1
Object 2 is a hoop of mass 1kg and radius R2
Object 3 is a disk that is mounted on a frictionless axle through its CM. It has mass 4kg and radius R3 (this disk acts as a pulley. It only rotates)
Note: ropes are attached to axles through CM’s
Theta = 30 degree
Phi =60 degree
Find the acceleration of mass 2.
