0.05 kg
20 kg

Answer 1

To find the mass of the object, we can use the formula for momentum:

\[ \text{Momentum} = \text{mass} \times \text{velocity} \]

Given:
- Momentum = \( 100 \, \text{kg} \cdot \text{m/s} \)
- Velocity = \( 5 \, \text{m/s} \)

We can rearrange the equation to solve for mass:

\[ \text{mass} = \frac{\text{Momentum}}{\text{Velocity}} \]

Substituting the given values:

\[ \text{mass} = \frac{100 \, \text{kg} \cdot \text{m/s}}{5 \, \text{m/s}} = 20 \, \text{kg} \]

Therefore, the mass of the object is **20 kg**.
