Ok well I just started some bullshit about kibetic energy and joules and I'm totally lost heres one of the problems...
The mass of the average car is around 1,500 kg. What is the kinetic energy in joules associated with the average car traveling on the interstate at 65 mi/h (29 m/s)?
PLEASE EXPLAIN HOW TO SOLVE! PLEASE!!

kinetic energy is (mv^2)/2
Plug and chug
((1500 kg)(29 m/s)^2)/2=? (in joules)

The kinetic energy of any body is half the product of the mass times the square of the velocity. In this example, multiply 29 by 29, multiply that by 750 (remember the half!), and you have it, as measured in joules.

its got to be a lot because im not a rocket scientist but the car is moving fast and 1500 kg seems like it would be a lot of weight, I know when I ran my car into the side of a building it hurt and my car was totaled, I hope that helps.

nicely i think of all my contacts are appealing of their very own way yet there is that this one touch in specific i'm beneficial could make my feet curl. he's that the form of beneficial respectful, clever guy or woman...i'm beneficial i will see him next existence time....in line with risk we are going to be butterflies!
