A 0.25 kg mass M attached to a spring with K= 100n /m is executing a simple harmonic motion on a frictionless table. The amplitude of oscillation is A=0.2 m What is the period of oscillation? If at time t=0 the mass is at x=0 and moving to the left write the equation using the ideal gas law derive a formula for the pressure p in terms of the density p and Vrms.
