A 0.31 kg cart (M) on a horizontal air track is attached to a string, which passes over a disk-shaped pulley of mass 0.080 kg and radius 0.012 m, and is pulled vertically downward with a constant force of 1.1 N. Find the acceleration of the cart and the tension in the string between the pulley and the cart. Include neat, labeled force diagrams, and all the steps of you derivations.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
