PRACTICE / Energy in SHM
How fast is an oscillator halfway to an end?
A particle undergoes ideal simple harmonic motion with amplitude A and angular frequency ω. At one instant its displacement from equilibrium is A/2.
What is its speed as a fraction of the maximum speed?
Organize the givens & assumptions
- Amplitude: A
- Displacement: A/2
- Maximum speed: ωA
Undamped one-dimensional SHM. The requested speed is a magnitude, regardless of the direction of travel.
- A
- B
- C
- D
