Ablock of mass m=0.750 kg is fastened to an unstrained horizontal spring whose spring constant is k=82.0 n/m. the block is given a displacement of +0.120m, where the + sign indicates that the displacement is along the +x axis, and then released from rest. c) what is the maximum speed of the block? group of answer choices

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
