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

Answer:

4.5 metres

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.

$900=200x\\x=4.5$
