The angle "phi" represents the phase shift, determined by the initial conditions of the experiment or the position of the weight at t = 0. if the weight is at its maximum positive position (weight is above equilibrium) at t = 0, then "phi" = 0. if the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then "phi"=pi . if the weight is traveling in the negative direction and passing through equilibrium at t = 0, then "phi"=pi/2. in the response box, describe the initial condition of our experiment; specifically, describe the position of the weight and the direction in which it was traveling.
