if a hard sticky mud ball is trown on a wall it sticks to it(adsbygoogle = window.adsbygoogle || []).push({});

it is an inelastic collision

K.E. is not conserved

but here momentum is also not conserved because mud had an initial velocity

so initial momentum of mud + initial momentum of wall (that is 0) = initial momentum of mud

final momentum of mud (that is 0 or less than its initial momentum)+final momentum of wall= 0 or less than total initial momentum

please explain hiw momentum is conserved here??
