Y(t) = sqrt(29)*sin(4pi t+68.2) The angle fi 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 fi = 0. If the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then fi = pi. If the weight is travelling in the negative direction and passing through equilibrium at t = 0, then fi = 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 travelling.

both equations and proportions are better.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

make sure you have version 2.50

try looking in the very back of the book : )
