The angle o 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 o = 0. If the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then o = pi. If the weight is traveling in the negative direction and passing through equilibrium at t = 0, then o = 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.

initially t=0

c2*sin0+c1*cos0

y=0+c1

y=c1

Initially the weight is in a resting motion. This is then changed when the weight is pushed backwards, similarly to a spring being recoiled.

Using this you should find the value of both c1 and c2 as I'm not fully versed in Math; however, it shouldn't be to hard.

Answer

 initially t=0 => c2sin(0)+c1cos(0) => y=0+c1 =>  y=0+5 => y=5

The weight was approaching the equilibrium position from the positive direction. The weight was on its way down, with the spring stretching

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
