Question 13 (1 point) /_//. 1/ '/' The perpetual motion of this weight, hanging from a spring, moving up and down, is described by the equation: x(t) = X0 + asin(oot) + bcos((1)t) where x(t) is the position of the weight in the vertical direction as a function of time, X0 is the resting position if the motion were to be stopped, to is the frequency of oscillation, and a and b are constants
