Question

A spring is oscillating so that its length is a sinusoidal function of time. Its length varies from a minimum of 10 cm to a maximum of 14 cm. At t=0 seconds, the length of the spring was 12 cm, and it was decreasing in length. It then reached a minimum length at time t= 1.2 seconds.

Between time t=0 and t=8 seconds, how much of the time was the spring longer than 13.5 cm?

Answer 1

Hello.

Answer 2

hi

Answer 3

Do you know how does a cosine graph look?

Answer 4

yes it starts at its amplitude then back down

Answer 5

cosine is the bottom

Answer 6

We can also say that it starts at its maximum, then decreases to reach the minimum point, then comes back up to the maximum.

Answer 7

Never mind my last comment
How about sine graph?
