1. The problem statement, all variables and given/known data Two blocks with masses m1=4.0kg and m2=5.0kg are connected by a light rope and slide down a frictionless wedge. The angle of the side on which m2 is moving is 53 degrees, and the angle of the side on which m1 is moving is 37 degrees. Basically the system looks like a triangle with the masses sliding down the two sides. If the system starts from rest, what is the speed of m2 after it has moved 40.0cm along the incline? GIVEN: m1=4.0kg m2=5.0kg d2(displacement of mass 2)=40.0cm 2. Relevant equations Ek= 1/2mv^2 Eg=mgh 3. The attempt at a solution I know that in this situation, the acceleration is going to be towards m2 so m2 is going to lose gravitational potential energy and gain kinetic. I know that m1 is going to gain gravitational potential energy and lose kinetic energy. I also know that the energy is conserved. I could calculate Eg for m2 but im not sure if i would use 40.0cm for the height.
