The momentum of an object can be calculated by multiplying its mass (m) by its velocity (v). In this case, the mass of the body is 10 kg, and its velocity is 5 m/s.
The momentum (p) is given by:
p = m * v
Substituting the given values:
p = 10 kg * 5 m/s p = 50 kg·m/s
Therefore, the momentum of the body is 50 kg·m/s.
