Expert Answer:

E n e r g y space s t o r e d space i n space t h e space s t r i n g space equals K over 2 x squared
I n i t i a l space e x t e n s i o n space K x equals m g
fraction numerator m g over denominator a end fraction x equals m g
x equals a
N o w space a d d i t i o n a l space 2 a space o f space e x t e n s i o n
S o space e n e r g y space s t o r e d space i n space t h e space s t r e c h e d space s t r i n g
K over 2 left parenthesis 3 a right parenthesis squared space fraction numerator m g over denominator 2 a end fraction left parenthesis 3 a right parenthesis squared
fraction numerator 9 m g a over denominator 2 end fraction
A s space p e r space w o r k space e n e r g y space t h e o r e m space a l l space t h i s space e n e r g y space c o n v e r t e d space i n t o space P E left parenthesis T a k i n g space t h e space l o w e s t space p o i n t space a s space t h e space p o i n t space o f space r e f r e n c e right parenthesis
fraction numerator 9 m g a over denominator 2 end fraction equals m g h
h equals 4.5 a
