A 12.0-N object is oscillating in simple harmonic motion at the end of an ideal vertical spring. Its vertical position y as a function of time t is given by y(t)=4.50cmcos[(19.5s−1)t−π/8].(a) What is the spring constant of the spring?

465.6 N/m

Explanation:

We are given that

F=12 N

We have to find the spring constant of the spring.

Where

Using the formula

kg

Compare the given equation with

We get

Using the formula

Spring constant,
