When the brick is at rest, the spring is stretched by 7 cm. The spring is then stretched an additional 4 cm and released. Assume there is no air resistance. Note that the acceleration due to gravity, , is  cm/s.Set up a differential equation with initial conditions describing the motion and solve it for the displacement  of the mass from its equilibrium position (with the spring stretched 7 cm).cm (Note that your answer should measure t in seconds and s in centimeters.)If you know how to do this problem please post your email so I can email you also! thankssss!!</blockquote>
