Please Help Could Not Solve A 0.60 kg mass attached to a spring with a constant k undergoes simple harmonic motion as it moves horizontally on a frictionless surface as shown below in the graph.

a. What is the amplitude of this mass. Explain how you determined your answer.

b. What is the period of motion of the spring-mass system? Explain how you determined

your answer.

c. Determine the spring constant k for the system.

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong

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)
