A23.0 kg block at rest on a horizontal frictionless air track is connected to the wall via a spring. the equilibrium position of the mass is defined to be at x=0. somebody pushes the mass to the position x= 0.350 m, then lets go. the mass undergoes simple harmonic motion with a period of 4.10 s. what is the position of the mass 3.403 s after the mass is released?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
