Question

A physics lab demonstrates the principles of simple harmonic motion (SHM) by using a spring affixed to a horizontal support. The student is asked to find the spring constant, k. After suspending a mass of 255.0 g from the spring, the student notices the spring is displaced by 33.5 cm from equilibrium. With this information, calculate the spring constant.

Provide this answer in N/M.

The student realizes that the spring demonstrates SHM with the attached mass of 255.0 g. The student is next asked to calculate the period of oscillation, T, neglecting the mass of the spring.

Provide this answer in s.

For the final section of the lab, the student is asked to investigate the energy distribution of the spring system described above. Calculate the velocity and potential energy for each displacement given and insert the correct answer using the "choices" column (scroll down to see table).

You need to put the correct values into the blank columns of Velocity and potential from the choices in the choices column. Displacement is given

Displacement values are 33.5 and 21.5.

Need to determine Velocity and Potential Energy (J)

Choices are:

0.173

4190

0

1.39

0.419

1.81

Explanation / Answer

so k = 0.335 * 9.81 / 0.335 = 9.81 N / m

b) T = 2 * pi * [m/k]^0.5 = 1.161 s
