Suppose that instead of steel balls we use putty balls. They will collide inelastically and remain stuck together after the collision. How high will the balls rise after the collision?

**Damon**, Friday, March 2, 2012 at 1:55pmTo conserve both momentum and energy, the first ball stops and the second one continues with the total energy.

In part 2, momentum is conserved but the motion continues with twice the mass.

m g (.29)(1-cos 25) = .5 m v^2

solve for v

then conservation of momentum at bottom

(m+m) * new v = m v

new v = (1/2) v

then at top

g (.29)(1-cos A) = .5 (new v)^2

solve for A
