Question

Physics question!!!

Mark weighs 600 N and is hanging from a bungee cord which is stretched a distance of 3 m how much would the same bungee cord stretch under the load of Chris who weighs 900 N?

Answer 1

4.5 metres

Step-by-step explanation:

Using Hooke's Law (
`F\propto x`)

We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.

`600=3k\\k=200`

Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.

`900=200x\\x=4.5`
