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
I think that’s right, hope it helps!:) brainliest??
