2 equel mass balls with equel velocity is thrown towards each other, what will happen???Momentum conserved????

net force along horizontal direction is 0 ...

net force along vertical direction is present ,that is gtravity ...

now , no external force acts on the system along horizontal direction so

horizontal momentam will remain conserved any time...

net force acts in verticle direction so verticle momentam changes with time...

Approved

In all the collisions, i.e. elastic, inelastic, superelastic etc. net momentum is conserved in the direction there is no external force.

hi,

when there is no external force acting on a system then net momentum will be conserved.before collision the net  momentum is mv-mv=0 then just after the collision the momentum will be 2mv1. as 2mv1=mv-mv(conservation of momentum) new velocity will be 0         

plzzzzzzzzz approve!!!!!!!!!!!!!!!!!!!!!!!!!
