Answer:
1.02s
Explanation:
In this situation the following equation will be useful:

Where:
 is Marissa's car final velocity
 is Marissa's car initial velocity
 is Marissa's car constant acceleration (assuming this is the acceleration, since 1269 m/s^{2} does not make sense)
 is the time it takes to accelerato from  to 
We can use the conservation of energy to solve this problem.
We know the bullet goes in at 39m/s and leaves with 27m/s and some energy lost. We can model this using the kinetic equation energy.
The "U" is the energy lost when the bullet went through the bag. Solving for U, we get:
Next we know the bag is 48cm thick and that F*d=W, rearranging this equation we get:
F = 12.375N
Exercise is a vigorous activity that tends to help us to burn calories and loose weight in the process.
<h3>What is exercise?</h3>
Exercise is a vigorous activity that tends to help us to burn calories and loose weight in the process. There is no quick way to loose weight because the calories were added on gradually and must also be lost gradually.
Before and after photos does not show the loss in calories. This can only be determined by measurement.
Before you buy exercise equipment;
- Ensure that the equipment meets your unique needs
- Ensure that you can afford it
- Ensure that you have enough space to contain the equipment
An example of an exercise equipment is a stationary bicycle. It works when you sit or stand on it and cycle repeatedly though it doesn't move. I am skeptical about it because it may not help you burn a lot of calories except you use it for long periods of time.

Answer:
A) Inertia
Explanation:
Inertia is why objects tend to resist changes in their motion. Like a rolling ball will keep rolling unless we try to add friction to it, which then would stop the ball.
Answer:
3g/cm³
Explanation:
<em>Use the formula:</em>
density = mass ÷ volume
<em>Substitute (plug in) the values:</em>
density = 3 ÷ 1 = 3g/cm³
