1. (not from the text) Damped Harmonic Motion: (2 points)
y= e cos(2neft)
Note: The cos(2neft part is simple harmonic motion. The e part is exponential decay.
The net result should be harmonic motion with amplitude that decreases with time.
k= 3 (units of /s or s')
f=4 Hz
Plot y vs. t
Add a title to the plot (e. g., "Position vs. Time").
Label the t and y axes. Include the units of seconds (s) on the time axis.
Note: Here, y is dimensionless. If y had some initial starting amplitude A, then that
would contain the units on y (e. g., meters m).
Tip: For a starting point, try t=0 to 5s, in 0.01s increments.
