The best leaper in the animal kingdom is the puma, which can jump to a height of 4 m when leaving the ground at an angle of 45 degrees.
a) with what speed must the puma leave the ground to reach that height?
b) How far does the puma jump horizontally?

for part a I got 12.62 for the speed.

I am not sure how to solve part b...what equation should I be using? and is the acceleration supposed to be zero for the x component? thank you

To function, the brain requires oxygen, nutrients and stimulii: these could be provided by external mechanical support.
- Could we remove a brain from a body and keep it "alive" that way? (serious question)
- Assuming we could, how long could the brain survive?

5x-6 <= 3(2+3x)
5x-6 <= 6+18x --- drop 5x from both sides
-6 <= 6+13x --- subtract 6 from both sides
-12 <= 13x

-12/13 <= 13x/13

.923 <= x
did i do this correctly?
