| Apr 24, 2014 at 23:20 | comment | added | John Alexiou | I think this is a valid question, given the posters age and experience. He/she want to know if it is possible (and how) to calculate the speed of the car from the evidence. | |
| Apr 24, 2014 at 21:22 | comment | added | David Z | @user45198 Sure, we understand this is not a homework assignment, but any sort of question where people just ask us to calculate something for them is what we call "homework-like", and is off topic here. Better questions are those that ask about some conceptual misunderstanding - so, for instance, you calculated the answer yourself but you're confused about why some particular step works. | |

| Apr 24, 2014 at 18:48 | comment | added | user45198 | Hi thanks for answering my question. It's not my homework I just wondered how fast the car was going that hit us. I wondered if since we were stopped if the car that hit us was going faster or slower than we hit the car in front if us. My mom added the part about kinetic energy because she is trying to teach me about science lol!!! I am ok but got a big bump on my head. | |
| Apr 24, 2014 at 18:45 | comment | added | Photon | The question is not so easy to answer since the kinetic energy is not conserved, I think, it is quite an effort to make an educated guess on the initial velocity of the SUV. | |
| Apr 24, 2014 at 18:42 | comment | added | David Z | @Photon well, but if that's all user45198 is asking, this would qualify as a no-effort homework-like question under our policy. I want to think there is something more here. | |
| Apr 24, 2014 at 18:39 | comment | added | Photon | The asker wants to know the initial velocity of the SUV. | |
| Apr 24, 2014 at 18:38 | comment | added | Sensebe | @DavidZ: Probably the user wants to know the meaning of absorption of kinetic energy. | |
| Apr 24, 2014 at 18:25 | comment | added | David Z | Hi user45198, and welcome to Physics Stack Exchange! It's not clear to me what you're actually asking here; could you clarify that? Are you asking whether it's possible that the car behind you sped up your car to faster than it was already moving? | |
