1. during a collision, the person not wearing a seatbelt is already in motion. there is no outside force (the seatbelt) to stop this motion.
2. Kinetic Energy = 0.5 * m * v^2 because velocity is a squared term, doubling the velocity actually quadruples the kinetic energy, making the stopping distance much much greater
3. by the same logic as above, mass is not a squared term, therefore doubling the mass will double the kinetic energy, increasing the stopping distance -- but by not as much as increasing the velocity.
4. because a driver cannot alter the mass of his vehicle, the best way to enter sharp curves would be decreasing velocity (speed)
5. there are many factors that determine the degree of damage (to humans and property in a crash), most notably the size of the vehicle(s) and velocity.

Answer:
Examine the sources cited by the website
Explanation:
Due to the ability for everyone to create a website, and that there are no governing standards on the quality of information given on websites, it is important when conducting research to ensure that the sources on the web are up to date, accurate, and provide an objective view
Therefore, it is important to go through and examine the website critically using the the following criteria
1) The website coverage
2) The currency of the website's information
3) Weather the website is objective or not
4) The identity of the author of the website and the ability to contact the author
5) The accuracy of the information contained in the website
Answer:
Explanation:
Renewable energy is fuel that comes from a source that can be replenished in a short amount of time. This includes solar, wind, water, geothermal power and bioenergy. While renewable energy sources may not always be available – for example, if there is no wind to drive wind turbines, or cloudy days that reduce solar energy – they play an important part in reducing the use of non-renewable resources. Furthermore, many of these resources do not emit greenhouse gases directly into the atmosphere.
