Another amplitude and oscillation problem

In summary, the conversation discusses a small earthquake causing a lamppost to vibrate with an amplitude of 6.5 cm at the moment the quake stops and 1.8 cm 8.0 seconds later. The conversation also introduces the concept of damped motion and asks for the time constant and amplitude of the oscillation 4.0 seconds after the quake stops. The homework equations are unknown and the attempt at a solution has not been made.

What do you know about damped motion, then? :confused:
 

Related to Another amplitude and oscillation problem

What is an amplitude and oscillation problem?

An amplitude and oscillation problem is a type of physics problem that involves the measurement and analysis of the amplitude and frequency of a periodic motion, such as a wave or a pendulum.

What are the key concepts related to amplitude and oscillation?

The key concepts related to amplitude and oscillation include the amplitude, which is the maximum displacement from the equilibrium position, and the frequency, which is the number of cycles per unit time.

How do you solve an amplitude and oscillation problem?

To solve an amplitude and oscillation problem, you need to identify the motion as simple harmonic motion, use the appropriate equations and values for amplitude and frequency, and then solve for the unknown variable.

What are some real-world applications of amplitude and oscillation?

Amplitude and oscillation have many real-world applications, such as in musical instruments, clocks, and earthquake monitoring devices. They are also used in the study of waves in different types of media, such as sound waves and water waves.

What are some common mistakes made when solving amplitude and oscillation problems?

Some common mistakes made when solving amplitude and oscillation problems include using the wrong equations, confusing amplitude and frequency, and not considering units when plugging in values. It is important to carefully read the problem and double-check your calculations to avoid these mistakes.
