+y T T +x T mg mg mg L20Bint. Interpretations for Simple Harmonic Motion of a Vertical Spring Part 1: Graphical Analysis 1. The fit coefficient that represents the angular velocity is B. 2. ω =2 /T π T=2 / π ω T=2 / π 9.017 1/s T=.697 s The period on the graph was about .70 s. This value is very close to period we found. 3. ω =(k/m)^(0.5) ω =((28.6 N/m)/(0.350 kg))^(.5) =9.03 1/s ω The angular velocity obtained here is close to the value used in number 2. 4. The equation of fit for position vs. time is x=0.0613 m*(sin(9.017 1/s*(t)+1.516))+0.8197 m. Thus the amplitude is 0.0163 m and the equilibrium position is 0.8197 m. 5. Vertically up is the positive direction. 6. When the mass has its greatest positive displacement, I expect the value for the velocity to be zero, because it should be slowing down to zero to go in the other direction. My velocity graph agrees with this prediction. 7. I expect the acceleration to be negative. My acceleration graph agrees with my prediction. This is because the mass is slowing down to move in the opposite direction. Acceleration at this time has reached its greatest value in magnitude.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
