Coba jelasin Head-on collision (1 dimensional) dari Moméntum dalam bahasa sunda dong

In the case of two objects colliding héad on we find that the final velocity

which can then éasily be réarranged to

Now consider the case when the mass of one body, say m1, is far gréater than that of the other, m2 (m1>>m2).

In that case m1+m2 is approximately equal to m1 and m1-m2 is approximately equal to m1.

Using these approximations, the above formula for  reduces to .

Its physical interpretation is that in the case of a collision between two bodies, one of which is much more massive than the other, the lighter body ends up moving in the opposite direction with twice the original speed of the more massive body.
