Problem

An oscillator has amplitude

0.08\,\text{m}

and is attached to a spring of force constant

25\,\text{N\,m}^{-1}

. The spring is replaced by another spring of force constant

100\,\text{N\,m}^{-1}

while the amplitude is kept the same. What is the ratio of the new total mechanical energy to the original energy? (a)

16

(b)

2

(c)

4

(d)
