Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Definition of Impulse
- $$t$$ is time
Impulse is defined as the product of force and the time interval over which the force is applied. The formula for impulse is: Where:
Step 3:: Analyze the Units
- Time ($$t$$) is measured in seconds ($$\mathrm{s}$$)
Let's break down the units:
Step 4:: Calculate the Units of Impulse
\text{Impulse Units} = (\mathrm{kg} \cdot \mathrm{m/s^{2}}) \times \mathrm{s} = \mathrm{kg} \cdot \mathrm{m/s}
Step 5:: Compare with Given Options
Looking at the options, $$\mathrm{kg} \cdot \mathrm{m/s}$$ corresponds to option A.
Final Answer
A. \mathrm{kg} \cdot \mathrm{m/s}
