The acceleration of the car at impact is 15m/s².
<h3>What is Newton's Second Law of Motion?</h3>
Newton's second law provides a precise explanation of the modifications that a force can make to a body's motion. According to this, a body's momentum changes at a rate that is equal to the force acting on it over time in both magnitude and direction. A body's momentum is equal to the sum of its mass and velocity. Similar to velocity, momentum has both a magnitude and a direction, making it a vector quantity.
acceleration - rate of change of velocity with time, both in terms of speed and direction. A point or object going straight forward is accelerated when it accelerates or decelerates.
There are three types of accelerated motions :
- uniform acceleration,
- non-uniform acceleration
- average acceleration.
express all the units in their most basic form.
kg, newton = kg*m/s², acceleration =m/s²

Answer:
Compounds can be broken apart in chemical reactions called decomposition reactions. For example, water can be broken down into the diatomic elements hydrogen gas and oxygen gas in a chemical reaction called electrolysis. ... Some compounds undergo thermal decomposition when they are heated.M
If you are charged to manage a project that aims to install wireless access points (aps) throughout the university campus, the steps to a foolproof plan for this project would be -
1. Recognize all of your network’s needs.
The most crucial step in any WiFi installation is probably knowing what your network needs are.
2. Select the appropriate hardware for your wireless network
Finding the ideal access point is much simpler if your needs are clear, but the wide range of options might be difficult.
3. Recognize your devices’ network restrictions.
It’s crucial to keep in mind that other factors besides your Internet connection and network hardware might affect how well your network performs.
4. Take into account the various cables you’ll need to use.
5. Consider how nearby interference may affect the installation of your wireless access point.
6. Decide where to put your wireless access point.
7. Analyze signal strength prior to making a decision.

Answer:
the Gravitational potential energy is 13.23 J
Explanation:
The computation of the GPE is shown below:
GPE stands for Gravitational potential energy
The following formula should be used for the same
= mass × gravity × height
= 3000 g × 9.8m/sec^2 × 0.45 m
= 13.23 J
Hence, the Gravitational potential energy is 13.23 J
We simply applied the above formula so that we can easily determine the GPE
