Answer
given,
mass of spring, m = 1.12 Kg
spring constant , k = 32.3 N/m
speed. v = 3.58 m/s
a) Kinetic energy of the spring
![KE = \dfrac{1}{2}kA^2](https://tex.z-dn.net/?f=KE%20%3D%20%5Cdfrac%7B1%7D%7B2%7DkA%5E2)
the mechanical work done by the spring
![KE = \dfrac{1}{2}mv^2](https://tex.z-dn.net/?f=KE%20%3D%20%5Cdfrac%7B1%7D%7B2%7Dmv%5E2)
now,
![\dfrac{1}{2}kA^2=\dfrac{1}{2}mv^2](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7DkA%5E2%3D%5Cdfrac%7B1%7D%7B2%7Dmv%5E2)
![A^2 = \dfrac{mv^2}{k}](https://tex.z-dn.net/?f=A%5E2%20%3D%20%5Cdfrac%7Bmv%5E2%7D%7Bk%7D)
![A^2= \dfrac{1.12\times 3.58^2}{32.3}](https://tex.z-dn.net/?f=A%5E2%3D%20%5Cdfrac%7B1.12%5Ctimes%203.58%5E2%7D%7B32.3%7D)
A =0.666 m
Amplitude of Oscillation = 0.666 m
b) Total mechanical work done by the spring
E = 7.17 J
He had their masses and reactivity. I hope this helps.
