A 2.0 g spider is dangling at the end of a silk thread. Youcan make the spider bounce up and down on the thread by tappinglightly on his feet with a pencil. You soon discover that you cangive the spider the largest amplitude on his little bungee cord ifyou tap exactly once every second
What is the spring constant of the silkthread?

Respuesta :

Answer:

The spring constant is [tex]7.89\times10^{-2}\ N/m[/tex]

Explanation:

Given that,

Mass of spider = 2.0 g

Period of oscillation = 1.0 sec

We need to calculate the spring constant

Using formula for simple harmonic oscillator

[tex]T=2\pi\sqrt{\dfrac{m}{k}}[/tex]

[tex]k=((2\pi)^2)\dfrac{m}{T}[/tex]

Where,

m = mass

T = time period

Put the value into the formula

[tex]k=(2\pi)^2\times\dfrac{2.0\times10^{-3}}{1.0}[/tex]

[tex]k=0.0789\ N/m[/tex]

[tex]k=7.89\times10^{-2}\ N/m[/tex]

Hence, The spring constant is [tex]7.89\times10^{-2}\ N/m[/tex]
