## Homework Equations

what is the change in velocity?

So you've found the momentum through impulse, how is momentum related to velocity?

Impulse, I=F*t= change in momentum= mΔv.

I guess now you know how to solve the problem.

## What is the equation for calculating change in velocity?

The equation for calculating change in velocity is: change in velocity = net force / mass * time.

## What do the numbers in the given values represent?

The number 5.02N represents the net force, 4kg represents the mass, 23.3s represents the time, and 116.966N*s represents the change in velocity.

## How do you convert the given values to the standard units of measurement?

To convert the given values to the standard units of measurement, you can use the following conversions:
- 1 Newton (N) = 1 kg*m/s^2
- 1 kilogram (kg) = 1000 grams (g)
- 1 second (s) = 1000 milliseconds (ms)
Using these conversions, the given values can be converted to:
- 5.02 N = 5.02 kg*m/s^2
- 4 kg = 4000 g
- 23.3 s = 23300 ms
- 116.966 N*s = 116.966 kg*m/s

## What is the significance of calculating change in velocity?

Calculating change in velocity is important because it helps us understand how an object's velocity is affected by external forces. By knowing the change in velocity, we can predict how an object will move and how much force is required to change its velocity.

## What factors can affect the accuracy of the calculated change in velocity?

The accuracy of the calculated change in velocity can be affected by factors such as air resistance, friction, and the reliability of the given values. Other factors such as the object's shape, surface area, and external forces can also impact the accuracy of the calculation.
