A pulley is pictured to the right. Its moment of inertia is 1.43 kg•m². A massless rope is wound around the pulley at a radius of 0.333 m. Two envelopes are attached to the pulley, as indicated in the picture. The first envelope contains the physical representation of the benefits of taking PHYS 1800, weighing 36.02 kg. The second envelope contains the physical representation of the costs of taking PHYS 1800, weighing 5.33 kg. (Note: the benefits of taking PHYS 1800 outweigh the costs). 2 Assuming no friction or air drag, what is the CCW angular acceleration of the pulley? Include units in SI. Answer:

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
