Answer:
Step-by-step explanation:
x = 0.6 m
F = 78 N
Let k be the spring constant.
F = k x
78 = 0.6 k
k = 130 N/m
(a)
x = 5.5 m
W = 0.5 kx²
W = 0.5 x 130 x 5.5 x 5.5
W = 7865 J
(B) x = 1.5 m
W = 0.5 kx²
W = 0.5 x 130 x 1.5 x 1.5
W = 146.25 J
This represents the values of k^2 from 2 to 8.
Im sure you can C the answer from this.
