Trying to verify these work relations

In summary, the conversation is about verifying work relations Wtotal = ΔK, Wc = -ΔU, and Wnc = ΔE. The problem involves a block of mass 2.40 kg connected to a second block of mass 1.80 kg, starting from rest and moving with a speed of 2.05 m/s before the second block hits the floor. The first three parts of the question have already been answered, with the values for distance, Wc, and Wnc being 0.937m, 16.5J, and -7.72J respectively. A diagram would be helpful in understanding the problem.

I need to verify these three work relations and don't know where to even start.

Wtotal= ΔK, Wc= -ΔU and Wnc = ΔE


The details for the whole problem were A block of mass m1 = 2.40 kg is connected to a second block of mass m2 = 1.80 kg, as shown in the figure. The two masses start from rest and are moving with a speed of 2.05 m/s just before m2 hits the floor.

I already figured out the answers to the first three parts of the questions and the answers were.

d=0.937m
Wc=16.5J
Wnc=-7.72J

Honestly I'm not sure what they are even looking for as means for an answer.

It would help if you could give us a diagram.

I apologize, I knew I forgot something.
