part d
write in the form and identify the amplitude, angular frequency, and the phase shift of the spring motion. record your answers in the response box.
part e
the angle 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 = 0. if the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then . if the weight is traveling in the negative direction and passing through equilibrium at t = 0, then . 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.
part f
find the times (to the nearest hundredth of a second) that the weight is halfway to its maximum negative position over the interval . solve algebraically, and show your work and final answer in the response box. hint: use the amplitude to determine what y(t) must be when the weight is halfway to its maximum negative position. graph the equation and explain how it confirms your solution(s).

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
