Science & Mathematics - 5 October 2007

I'm reading a book and one of the characters has some DNA of a bear, and he carries around this book with pressed flowers, and momentos of every place he's ever been in his life. He doesn't seem to have a firm grip on reality, and whenever someone asks him a question about something, he gets out his book and verifies what they were talking about. Sense he has some DNA of a bear, I think it might be related to that... Any answers?

A driver traveling at 59 km/h sees a chicken dash out onto the road and slams on the brakes. Accelerating at -7 m/s2, the car stops just in time 24.0 m down the road. What was the driver's reaction time (i.e., the time that elapsed before he engaged the brake)?

It's the last problem of my homework, and I just want to be done. Help appreciated!

I was on the pill but ended up with a blood clot in my eye. As a diabetic I have to be careful about getting pregnant. I looked into the IUDs but they don't suggest them for women who have not had children yet.

IDK, but I find it much easier writing an equation in point slope form.
The question was write a standard form equation for a line who's slope is 2 and that passes through the point (3,1)

So my answer in point-slope form is
y=2x-5

I heard someone say there's way to convert the point slope form to a standard form, but I'm not sure if this is possible. Please explain how to write it into standard form =]

the particle has the given acceleration, initial velocity and position:
a(t)= 16i+48tj+84t^2k
v(0)=i
r(0)=j-k

A. Find the velocity vector
B. Find the position vector

ok i know that a(t)=v'(t) and v(t)=r'(t)
i thought i could just take the antideriv of a(t) and then v(t) but i didn't get the right answer.
