Homework Statement
I doubt energy is conserved in SHM, or it might be possible that i be doing something wrong.
The particle (red dot) in the attachment is at its equilibrium position and oscillates with Simple Harmonic Motion between the two yellow colored plates.
Amplitude A = 1.5 m
Frequency = 3 Hz
Find the maximum speed of the particle
Homework Equations
Conservation of Energy
V = ω [itex]\sqrt{A^{2}-x^{2}}[/itex]
The Attempt at a Solution
This max speed occurs at its equilibrium position .
1st method (which leads to the correct answer) :
V = 9∏ meters per second
2nd method (explain why this is wrong when it makes perfect sense)
Total energy at highest plate (yellow) = total energy at equilibrium position
mg(1.5) = 0.5m[itex]v^{2}[/itex]
v = [itex]\sqrt{30}[/itex]
What is wrong with energy conservation method ?
