Problem 3: Consider the following piston cylinder assembly where the piston is resting on some stops.The spring is undeformed initially which just touches the piston. From this point, a net pressure acts on the piston exerted by the inside air and its magnitude is 193.7 kPa. This makes the piston to rise above the stops compressing the spring by 50 mm. Calculate the total work done by the air. Hint: Add the work done by the air and the spring work.Ans: 804J
