1. The problem statement, all variables and given/known data A 1kg object traveling at 1 m/s collides head-on with a 2 kg object initially at rest. If the collision is completely inelastic, determine a) the velocity of the objects after impact and b) how much kinetic energy was lost during the collision. 2. Relevant equations Part a) m1v1 + m2v2 = (m1+m2)v' Part b) ke before =1/2m1v1^2, ke after= 1/2 (m1 + m2)v2^2 3. The attempt at a solution Part a) m1v1 + m2v2 = (m1+m2)v' 1 + 0 = 3(v') v' = 1/3 Part b) KE before: 1/2 m1v1^2 .5 (1)(1^2) =.5 KE after: 1/2 (m1+m2)v2^2 .5(3)(0) = 0?????? KE Lost: (kinetic before - kinetic after)/kinetic before (.5-0)/.5 = 1???????
