Question

the velocity of a body of mass 5.0 kg reduce from 10 metre per second to 5 metre per second what is the change in momentum of a body ​

Answer 1

hey mate here is ur answer =

☆Initial momemtum =

P=mv=5×10=50kg.m/s

☆Final momentum =

p=mv=5×5=25kg .m/s

Change =25-50=-25kg.m/s

hope it helps.

Answer 2

Answer

25 kg.m /sec

Exploitation:

momentum = mass × velocity

velocity decreases 10m per sec to 5 m per sec

= 10 - 5 = 5m per sec

momentum = 5×5 = 25 kg.m /sec
