Consider two balls of identical mass. If ball 1 is moving to the right towards stationary ball 2 at 1.0 m/s and the two balls collide elastically, what will the final velocities of both balls be?
Wouldn't both balls just move in the right direction at 1.0m/s? Potentially attached to one another?

Best ResponseYou've already chosen the best response.1yoi need to dredge through the energy ad momentum equations to work these out  ie equating total momentum and kinetic energy before collision with total momentum and kinetic energy before collision but this can be a very handy shortcut or at least a change of scene. \(C_R\) is the coefficient of resititution and it equals 1 in an elastic collision dw:1442308533188:dw

Best ResponseYou've already chosen the best response.1although there isn't so much to do here as the masses are equal and the second ball is stationary before the collision dw:1442310011254:dw
