Momentum = mass x velocity
125 mkg/sec=25kg x velocity
Therefore, velocity= 125/25 =5 meter/sec.
Momentum: momentum is the product of the mass and velocity of an object.
It is a three-dimensional vector quantity, possessing a magnitude and a direction.
If m is an object's mass and v is the velocity (also a vector), then the momentum is: P=mv. In SI units, it is measured in kilogram meters per second (kg⋅m/s).
Newton's second law of motion states that a body's rate of change in momentum is equal to the net force acting on it.

Answer:
Mass of the body, m = 25 kg
Momentum p = 125 kg.m/s
p = m x v
125=25*v
v=5m/s
Velocity of the body is 5 m/s
