Two objects are connected by a string passing over a frictionless pulley. When the objects are in motion object A experiences a force of kinetic friction with a magnitude equal to 5.0 N. The mass of object A is 2.1 kg and the mass of object B is 3.3 kg

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?
