1. The problem statement, all variables and given/known data I already found A, but I keep getting wrong answers for B. A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 4300 N/m. The piston has a negligible mass and a radius of 0.017 m. (a) When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? (b) How much work does the atmospheric pressure do in compressing the spring? k= 4300 N/m r= 0.017 m A= 0.00091 m^2 P= 101 kN/m F= 91.995 N 2. Relevant equations P= F/A W= F d 3. The attempt at a solution I found the answer to A which is 0.0214 m. So then I tried to use the Work equation and got 1.969 J. But this is wrong. I'm stuck! Please help!
