The cylinder in the figure has a moveable piston attached to a spring. The cylinder's cross-section area is 10 cm2, it contains 0.0055 mol of gas, and the spring constant is 1500 N/m. At 15oC the spring is neither compressed nor stretched.
a) How far is the spring compressed if the gas temperature is raised to 170oC? Express your answer to two significant figures and include the appropriate units.
The potential energy function of a point mass is given by the expression: U(x) = 2x^2 - 8x, where x is the coordinate of the body and U is measured in Joules. Only conservative forces are acting. Find the kinetic energy of the body (in J) at the ..
