6. If momentum of an object is doubled what happens to its velocity? 
a) Doubled
b) becomes three times
c) No change

Dear Student,

Momentum is the product of mass and velocity where mass is constant for a particular body. So change in momentum for a particular mass is only depend on the change in velocity.

So the change in momentum for a mass “m” is equal to the change in velocity.

So because you double the momentum (2p) then velocity is also doubled, change by (2).

so option a is correct

hope it hepls.....
