An elastic band is hung on a hook and a mass is hung on the lower end of the band. when the mass is pulled downward and then released, it vibrates vertically. the equation of motion is s(t)=2cost+3sint, t≥0, where s is measured in centimeters and t in seconds. (we take the positive direction to be downward.) (a) find the velocity function. (b) when does the mass pass through the equilibrium position for
