Amass vibrates back and forth from the free end of an ideal spring of spring constant 20.0 n/m with an amplitude of 0.250 m. what is the maximum kinetic energy of this vibrating mass?

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.
