Question

A weight is attached to a spring that is oscillating up and down it takes 6 sec for the spring to complete one cycle and the distance from the highest to lowest point is 7 in what equation models the position of the weight at time t seconds.
a. y = 7sin ( (pie / 3)t)
b. y = 7sin ( (pie / 6)t)
c. y = 7sin (6(pie)t)
d. y = 3.5sin ( (pie / 6)t)
e. y = 3.5sin ( (pie / 3)t)
f. y = 3.5sin (6(pie)t)

I think that its e but I am not sure

Answer 1

That's <u>pi</u>, not pie! Grrr. Pie is what you eat.

The period is 6, so you start with y = sin(π/3 t), so the only choices are A and E
The amplitude is 3.5, so that makes it E.

Answer 2

mmm I could go for a good pecan pie right now.

Answer 3

Ans: E I did it
