A wave traveling on a Slinky® that is stretched to 4 m takes 4.97 s to travel the length of the Slinky and back again.(a) What is the speed (in m/s) of the wave? m/s

Respuesta :

ANSWER

1.61 m/s

EXPLANATION

Given:

• The distance the Slinky is stretched, d = 4 m

,

• The time it takes for the wave to travel the length mentioned before and back, t = 4.97 s

Find:

• The speed of the wave, v

We know that the wave takes 4.97 seconds to travel the 4 meters the Slinky was stretched and back, so it travels a total of 8 meters in that time. This means that the speed of the wave is,

[tex]v=\frac{2d}{t}=\frac{8m}{4.97s}\approx1.61m/s[/tex]

Hence, the speed of the wave is 1.61 m/s.
