An oscillator moves back and forth between the 10 cm and 50 cm marks on a meter stick.
What is the location of the EP on the meter stick?
In Problem 11, what is the amplitude A?
If you did the previous question right, you hopefully got an expression for yo. You may notice that
you can simplify the differential equation a little bit:
d'y
k
(y – yo)
dt2
т
The parameter yo now plays the roll of the "relaxed length". A better term may be "equilibrium value
for y". But mathematically, it's identical to a relaxed length with the spring as the only force. We
continue using this equation:
y(t) = Y0 + A cos(wt + y)
Now, solve for A (in cm) with these parameters. Again, if you need more information, enter
-100000. The parameters are:
•m = 200 grams
• Yo = (equilibrium value) = 40 cm
• k = (spring constant) = 0.03 N/cm
A 2.6kg mass is a attached to a spring with a stiffness of 410N/m. In the picture on
the left side, the system is in equilibrium. A student then displaces the spring
downward to the position as shown. Neglect friction and drag.
