1. The problem statement, all variables and given/known data With which speed goes the Mass through the Equilibrium? 2. Relevant equations Es = 1/2*D*s2 Ekin = 1/2*m*v2 Epot = m*g*h Energy in the zero point = below/ under highest Point: Epot = 1kg * 9,81N/kg*0.67m ≈ 6.573Nm Equilibrium : Ekin, Epot, Es Lowest Point: Es= 0 Ekin = 0, Epot = 0 3. The attempt at a solution I have no Idea what I have to do. I found out that the total Energy needs to be approx. 6,573Nm of the system.
