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 bellow equilibrium) at t = 0, then phi = 0, 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 of and the direction in which it was traveling
