Given: m = 25 kg
p = 125 kg. m/s
v = ?
we know momentum = mass (m) x velocity(v)
p = mv
125 = 25 x v
v = 125/25
v = 5 m/s
p = 125 kg. m/s
v = ?
we know momentum = mass (m) x velocity(v)
p = mv
125 = 25 x v
v = 125/25
v = 5 m/s

To find the velocity of the body, we can use the formula for momentum:
Momentum = mass × velocity
Given that the mass of the body is 25 kg and the momentum is 125 kg·m/s, we can rearrange the formula to solve for velocity:
velocity = momentum / mass
Substituting the given values, we have:
velocity = 125 kg·m/s / 25 kg
Simplifying the expression, we find:
velocity = 5 m/s
Therefore, the velocity of the body is 5 m/s.
Explanation:
The momentum of an object is the product of its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction. In this case, we are only given the magnitude of the momentum, which is 125 kg·m/s.
To find the velocity, we divide the momentum by the mass of the object. This is because velocity is defined as the rate of change of position, and momentum is directly proportional to velocity. By dividing the momentum by the mass, we can determine the velocity at which the object is moving.
In this problem, the mass of the body is given as 25 kg and the momentum is given as 125 kg·m/s. By dividing the momentum by the mass, we find that the velocity of the body is 5 m/s.
The correct answer is option A: 5 m/s.
