please could you just check my arithmetic please?

i know the parts just will you check my aritmatic? it's (K+U)initial=(K+U)final and i know all the spring constant parts with .5kx^2, mgh etc.

here is the image... A 20.0 kg block is connected to a 30.0 kg block by a string that passes over a light, frictionless pulley. The 30.0 kg block is connected to a spring that has negligible mass and a force constant of 240 N/m, as shown in the figure below. The spring is unstretched when the...
