Physics 211 10/23 HW Handout Due Friday 10/25 Fall 2002 Momentum and Energy 1) Block A slides to the right across a frictionless surface with speed v A,i and collides with block B , initially at rest. The mass of block A is m A = 2m and the mass of B is m B = 3m. a) In which of the following cases below is momentum conserved for the two-block system? Show all your work for each case. I suggest a separate page. Final Velocities c Bl oc k A Bl oc k B
