In a road accident where one car has stuck to another on collision, accident investigators often measure the length of skidmark produced from where the vehicles collided. The mass of the two cars and the deceleration produced by the road are also measured. How can these figures be used to calculate the velocity of te cars before collision? I got this question as homework after having had a Physics lesson on Momentum. Any help will be very much appreciated. Thanks.

Logic Puzzle?

1. Jim Fisk didn't go to Dr. P
2. 3 women visited Dr. N, are Ms. Falmer, and saw the derm.
3. Ms. Foster visited the surgeon
4. Orthopedists, who isn't french's doctor, is not Dr. C.
5. A woman went to Dr. A., but she wasn't Jean
6. Janet isn't woman who saw the obstetricain, who is not Dr. C
7. Jill's last name is Furnace

(the other things not stated are Dr. S. and an ophthamologist)

I'm pretty sure jack is french, but i keep getting an anomaly every time. ANY IDEAS? Thanks. I need to find out the first names, last names, doctor they saw, and the doctor's profession. All the information is given, you can get a single answer with it. It might be helpful to draw a grid, with 6 grids for all the combinations of categories. (any help will be greatly appreciated, however if you answer with something like "asdf" just for the 2 pts. you're breaking yahoo's terms and i will report you).

Guys look in nuclear fission involves in breaking of a heavier nucleus into lighter nuclei and in doing this the binding energy of nucleus is lost and hence enormous amount of energy is lost and i can understand that, but in nuclear fusion two or more nuclei combine to form a heavier nucleus and hence the binding energy should be acquired but rather its released, howcome this happens and i know that nuclear reactions occur in stars and the temperature required for the reaction is found to be of order 10 power 6 and during the beggining of formation of star, how did it attain that high temperature and it is easy to understand high temp. of stars coz of the energy released during fusion, however it is and one more doubt give me an example of fissile material apart from Uranium - 235 and 100% to points for the best answer. Thanks for answering if answered and hope for good answers coz i wud like to understand the subject.

For some positive constant, C, a patient's temperature change, T , due to a dose, D, of drug is given by

T = (C/2 - D/3) * D^2

a. What dosage maximizes the temperature change?

I tried to answer this question by finding dT/dD. But on question b the question is "The sensitivity of the body to the drug is defined as dT/dD. What dosage maximizes the sensivity?"
