Conservation of energy problem?

Byron Fortmann: A) Total energy lost E = m*g*dh = 5.000*9.8*(.25 - .21) = 1.96 JB) Ec = 0.700 J (this is given in the problem!)C) Ef = E - Ec = 1.26 J

Alisa Kaleiwahea: Conservation of energy says that energy cannot be created or destroyed, only transferred.A) Total Energy = Initial energy of the object = m*g*hi = 5 kg * 9.81 m/s^2 * 0.250 m = 12.3 JFinal energy = m*g*hf = 5 kg * 9.81 m/s^2 * 0.210 m = 10.3 JLoss = 12.3 J - 10.3J = 2 JB) .700 J C) Initial - Final - Bumper loss = 12.3 J - 10.3 J - 0.7 J = 1.3 J...Show more
