All about momentum...For the expert in Physics only... joking.....hope you'll answer :)?

A high speed bus and an innocent bug have a head-on collision. The sudden change of momentum fort he bug spatters it all over the windshield. Is the change in momentum of the bus greater, less or the same as the change in the momentum experienced by the unfortune bug?



This is a serious question... please help....hehe

Momentum must be conserved so the change in momentum for both must be the same. i.e. the momentum is the same for both but in opposite directions.



It is the relative different in Masses (i.e. the bus is probably over 1 million times heavier than the bug) and so it doesn't really notice the collision - but obviously the bug notices it more (but not for long though heh!).

the same
Of course, momentum is a form of kinetic energy and because the (poor) bug splattered, likely some of the bug's momentum was converted into thermal energy and momentum was not perfectly conserved...haha.
