Work out the extension of the spring, check the unit, plug it into the formula together with the spring constant.

Multiply by 32 to get the combined energy

how do you get the extension
The final length (17cm) minus the start length (5cm)

The extension is how much the spring has extended by, compared to its original length. You have the start and the end length.

E=1/2ke2
divide all cm by 100 to convert to m for extention
spring stretched by 0.12 (difference from non stretched)
E=1/2*5000*(0.12)^2
E=36j
36*32=1152
total E = 1152J
