I want to use the flash circuit to make a coil gun, but how dangerous is it? What will happen if I get shocled? Will it just hurt or will I die?

I'm just interested in what you people do when you answer math questions on the Mathematics Section of Yahoo! Answers.

I thought that maybe you people just answer the questions and focus on the task, but I usually listen to music and eat while I do my questions.

There's gotta be some people that do things more weird then that while answer questions.

Please tell me what you do when you answer question!! Hopefully this will get interesting.

Two forces, 474 N at 11± and 425 N at 32± are
applied to a car in an effort to accelerate it.

m=3395 kg
Force 1= 474 Newtons at 11deg above horizontal.
Force 2= 425 Newtons at 32deg below horizontal.

1) What is the magnitude of the resultant of
these two forces? Answer in units of N.

2) Find the direction of the resultant force (in re-
lation to forward, with counterclockwise con-
sidered positive).
Answer in degrees from the positive x-axis,
with counter-clockwise positive, within the
limits of -180deg. to 180deg. Answer in units of deg.

3) If the car has a mass of 3395 kg, what accel-
eration does it have?
Ignore friction. Answer in units of m=s2.

To stop a car you require first a certain reaction time to begin breaking; then the car slows under a constant breaking deceleration. Suppose that the total distance moved by your car during these two phases is 186 ft when its initial speed is 50mi/h, and 80 ft when the initial speed is 30 mi/h. What are a) your reaction time and b) the magnitude of the deceleration.

If you can answer this you are a genius.

Thanks in advance
