"A brick of mass 8 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 7 cm. The spring is then stretched an additional 3 cm and released. Assume there is no air resistance. Note that the acceleration due to gravity, Image for A brick of mass 8 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 7 c , is Image for A brick of mass 8 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 7 c = 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 7 cm).
s(t) = cm"
