Test: MCAT Physical

A 2kg mass is suspended on a rope that wraps around a frictionless pulley attached to the ceiling with a mass of 0.01kg and a radius of 0.25m. The other end of the rope is attached to a massless suspended platform, upon which 0.5kg weights may be placed. While the system is initially at equilibrium, the rope is later cut above the weight, and the platform subsequently raised by pulling on the rope.

1.

If we assumed the pulley had internal friction, how would the initial and final accelerations of the platform with the individual masses change?

Initial acceleration will decrease; final acceleration will increase

Initial acceleration will decrease; final acceleration will remain the same

Initial acceleration will iecrease; final acceleration will remain the same

Initial acceleration will remain the same; final acceleration will remain the same
