Please solve both

1 point) A brick of mass 6 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 4 cm and eleased. Assume there is no air resistance. Note that the acceleration due to gravity-g, is g 980 cm/s 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) s(t)4cos(18.07U/s) Note that your answer should measure t in seconds and s in centimeters.) cm (1 point) The IVP (6)y-sin() z2 1 has a unique solution defined on the interval
