Answer:
Elastic Potentional Energy is with the second answer
Mechanical Energy is with the last answer
Gravitational Potential Energy is with the first answer
Explanation:
Sorry this took so long it was a bit hard to remeber at first but I got it :)
Mark me as branliest if it is correct
A) 222 N/m
Explanation:
Hook's law gives us the relationship between force (F), displacement with respect to the original length (x) and spring's constant (k):
In this part of the problem, we have:
F = 120 N - 100 N = 20 N is the new force applied
x = 9.0 cm = 0.09 m is the displacement relative to the initial stretched position
Solving the equation for k, we find the spring constant
B) 45 cm
We can use Hook's law also for this part of the exercise:
where this time we have
F = 100 N (the original pull applied)
k = 222 N/m
Solving the equation for x, we find the original displacement:
