The momentum of an object can be calculated using the formula:
\[ \text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v) \]
Given that the mass (m) is 5 kg and the velocity (v) is 20 m/s, we can substitute these values into the formula:
\[ p = 5 , \text{kg} \times 20 , \text{m/s} = 100 , \text{kg}\cdot\text{m/s} \]
So, the momentum of the object is 100 kg⋅m/s.
