  1) As a stone slides down a frictionless, ice-covered hill, its mechanical energy is conserved but its momentum is not conserved. 2) Two cars collide, lock bumpers, and eventually slide to a stop due to friction with the roadway.  During this entire process, mechanical energy and momentum are both conserved. 3) Kinetic.
