Question
Greetings, I need a little assistance choosing the proper formulae tosolve this problem: "Two blocks are attached to a light rope that passes over africtionless pulley, suspended from the ceiling. The masses arereleased from rest and the heavier mass starts to descend. After this block has descended 1.20m, its speed, is 3.00m/s.If the total mass of the 2 blocks is 15.0kg, what is themass of each block?". Is it correct to use the formula: K1+ U1 + Wother = K2 +U2 Thank you!

Explanation / Answer
That should work: 1/2 (m1 + m2) V2 =(m1 - m2) g h where m1= 15 - m2
