v^2=u^2+2as
=2×10×0.8
v=(16)^1/2
v=4 m/s.
momentum(p)=mass×velocity
p=mv
p=10×4
p=40 kg m/s.


EnoshGonmei: But how??
hiteshpal: second law of motion se (v) ki value aa jaiyega
EnoshGonmei: Can you send its steps?
hiteshpal: momentum =m × v
EnoshGonmei: 'kay......Thanks!

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,,,,


Refer and consult the two following attachments for a detailed explanation and step by step solution along with vital elaboration for certain formulas we used ,,to arrive at a final conclusion that is,,,


\boxed{\bf{Momentum \: (P) = 40 \: Kg \: ms^{-1}}} \\


HOPE THIS HELPS YOU AND CLEARS YOUR DOUBTS FOR FINDING MOMENTUM USING SECOND LAW OF MOTION FORMULA!!!!!!!
