Angular Momentum
The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…
Moment of a Force
The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…
Question

I keep getting wrong answers for this question how do I do it?

A window cleaner is pulling himself up to a pulley that consists of two disks welded together as shown. The person is currently pulling straight down on the rope in his hands with a force of magnitude 562 N. The other rope is also vertical and is attached to the person's center of mass. The person's mass is 82.5 kg, the pulley's total moment of inertia is 5 kg · m?, the radius of the small disk is 0.4 m, and the radius of the big disk is 1 m. Acceleration What is the magnitude of the acceleration of the person's center of mass? а —
