Abrick of mass 4 kg hangs from the end of a spring. when the brick is at rest, the spring is stretched by 3 cm. the spring is then stretched an additional 2 cm and released. assume there is no air resistance. note that the acceleration due to gravity, g, is g=980 cm/s^2.
set up a differential equation with initial conditions describing the motion and solve it for the displacement s(t) of the mass from its equilibrium position (with the spring stretched 3 cm).
