Question

two object of same masses have the same momentum.which of them is moving faster

Answer 1

Both the objects will have the same velocity.
Proof
- Mass of first body = Mass of second body = m
Velocity of first body = v1
Velocity of second body = v2
Momentum is same
mv1= mv2
v1= v2
Proved

Answer 2

LET m1 and m2 be the masses of both the objects and v1 and v2 be velocities of the objects respectively
MOMENTUM means the product of mass and velocity,
so, if the momentum is same then
P1=P2 
=m1*v1=m2*v2
since mass is equal
therefore, v1=v2
