The final class cannot be extended because in java final keyword means "no modification". If it is applied to a variable or anything else then that value becomes a constant after that it cannot be modified.So in cases of class if final keyword is used it means that class cannot be extended.
Answer:
Explanation:
The formula for the work done on a spring is:

where k is the spring constant and x is the change in length of the string
For the first statement,
x = (a-1.1), W = 5
=> 
Now making k the subject of formula, we have:

For the second statement,
x = (a-4.8), W = 9
=> 
Now making k the subject of formula, we have:

Equating A and B since k is constant, we have:

solving for the value of a

solving for a, we get:
a = 2.6801 or -9.7301
but since length cannot be negative, a = 2.68m
substituting the value of a in equation B, we have:

k = 4.005
