Answer #1

Here,

as the total momentum of the system is conserved during collision

as there are no external forces acting during the collision on the bug+truck system

hence , the change in momentum of bug = change in momentum of the truck

therefore neither of them has greater change in momentum

the change in momentum is equal in magnitude
