#### Answer:

The

#### Explanation:

Assuming constant velocity and mass.

The change in force is equivalent to the force being applied currently subtracted from the force that will be applied.

Physics is always in **Kilograms, Meters, and Seconds** . So convert.

Use the equation to plug into our formula for
