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

Ideally, the smaller the sample population, the more accurate is the sampling result, but it will take longer time if the number of samples is huge.
The answer to the above question is ideally 20 light bulbs per sampling.
