Answer to Question #267110 in Mechanics | Relativity for Chan

Question

The spring oscillates to the other end. The amplitude is 3.5m, k = 1.2, and = 4.3 . Solve the frequency, wavelength, wave speed, period, wave number, and direction.

Answer 1

Wavelength:

$$\lambda=2\pi/k=5.2\text{ m}.$$

Frequency:

$$f=v/\lambda=4.3/5.2=0.83\text{ Hz}.$$

Period:

$$T=1/f=1.2\text{ s}.$$
