M2 = 0.800 kg that is initially at rest. No external forces act on the balls. a) What was the kinetic energy of the first ball before the collision; b) If the collision is completely inelastic, what are the velocities of the balls after collision?

**drwls**, Saturday, May 21, 2011 at 8:35pma) Can you calculate (1/2)M1*Vo1^2?

b) by "completely inelastic" I assume you mean that they stick together and momentum ios conseved.

Write and solve the momentum conservation equation to get the final velocity (the same for both masses).
