The SI unit of momentum is

Options

A. `(kg)/m`
B. `(kg.m)/(sec)`
C. `(kg.m^(2))/(sec)`
D. `kgxx"Newton"`

Answer

To find the SI unit of momentum, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Momentum**:
Momentum (p) is defined as the product of an object's mass (m) and its velocity (v). The formula for momentum is:
\[ p = m \times v \]

2. **Identify the SI Units**:
- The SI unit of mass (m) is the kilogram (kg).
- The SI unit of velocity (v) is meters per second (m/s).

3. **Combine the Units**:
To find the SI unit of momentum, we multiply the units of mass and velocity:
\[ \text{Unit of momentum} = \text{Unit of mass} \times \text{Unit of velocity} = \text{kg} \times \left(\frac{\text{m}}{\text{s}}\right) \]

4. **Express the Unit**:
Therefore, the SI unit of momentum can be expressed as:
\[ \text{Unit of momentum} = \text{kg} \cdot \frac{\text{m}}{\text{s}} = \text{kg m/s} \]

5. **Check the Options**:
If there are multiple-choice options provided, we would look for the one that matches "kg m/s".

### Conclusion:
The SI unit of momentum is **kilogram meter per second (kg m/s)**.
