The 3-lbs piece of putty is dropped 6 ft onto the 17-lbs block initially at rest on the two springs, each with a stiffness k = 2 lbs/in. calculate the additional deflection d of the springs due to the impact of the putty, which adheres to the block upon contact.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
