No Change as such

momentum= mass*velocity both remain same after collision so no change in momentum.

But how? Are we to add both the momenta?

adarsh see the direction change as well first it is +v next it is -v
anonymous

Okay. yeah, got it. First, Its MV. Second is -MV. Subtracting, we get 2MV.
anonymous
  • anonymous
By subtracting how we get 2MV
anonymous
  • anonymous
But I don't understand why the sign is +ive in first case and -ive in second case.
anonymous
  • anonymous
See, MV - ( - MV) = MV + MV = 2MV(Simple integer addition)

Can anyone say about the signs?
anonymous

|dw:1329838538143:dw|because we shud maintain a standard sign system like think this way

So, in all physics problems requiring direction, we need to follow Cartesian System, rite?
anonymous
  • anonymous
yeah there is more than that for that u need to come to 11th for now understand that when it is a 1-dimensuional(straight line motion) follow the co-ordinate axes
