Answer:
it remains same
Explanation:
p=mv
if new m= m/2
new v = 2v
new m *new v = m/2 *2v
=mv
thus the initial and final values wont change
hence it is same
Initially ,
Let the mass of the body be m and its velocity be v
hence the momentum is given by
P i= m v
Now,
the velocity of the body is doubled
v ' = 2 v
the masses is halved
m' = m / 2
New momentum ,
the momentum of the body remains the same
