9.448m

#### Explanation:

The mass has to be put in kg:

We will use the conservation of energy.

The energy put by the spring:

The energy for the gravitation:

If we apply the conservation of energy to this situation:

We put the three equations together:

We isolate the height (y):

We take all the values of our situation and put them in there:
