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.
