Answer:
1966 J
Explanation:
The work done by the hose on the balloon is equal to the elastic potential energy stored in it:
where
k = 130 N/m is the spring constant
x = 5.50 m is the stretching of the hose before it is being released
If we substitute these numbers into the equation, we find:
So, the work done is 1966 J.
