Two blocks with different mass are attached to either end of a light rope that passes over a light, frictionless pulley that is suspended from the ceiling. The masses are released from rest, and the more massive one starts to descend. After this block has descended a distance 1.30 m, its speed is 3.50m/s .
If the total mass of the two blocks is 14.0 kg, what is the mass of the more massive block?

Can someone help me get started with this problem? I'm not sure I am using the right equation or approaching it correctly
