### Re: "Can't Sleep" Discussion

Basically, if you add one to the highest possible number you can hold (32767 in a signed 16-bit integer), you'll overflow to the lowest possible number (-32768 in a signed 16-bit integer). The alt-text stresses the importance of using a 32-bit integer instead, which would stick the upper limit up i...

it's not a matter of remembering - it's a matter of only going to one website to do all my morning stuff. all Einstein's clothes were the same so he wouldn't have to decide what to wear, as he considered it a waste of thought. we all have different priorities.

for #12, I got 52, which sounds big V_{yf}=V_{yi}t-\frac{1}{2}gt^{2} to solve for t (we don't want the negative time here, so solving the quadratic I got 3.21 seconds) then I used t in the range equation to solve for the distance traveled in the x-direction. try it that way and see if I made a mista...

But you don't need the parabola.

You have the initial velocity and the angle, and the height of the cliff.

Which equation can you plug those into and get only one unknown?

resotpvl wrote:so would the answer to #12 be 38.82m

I got a larger answer.

I figured out the x- and y-components of the velocity

then I used [imath]y=v_{o,y}*t+0.5*a_{y}*t^{2}[/imath] to get the time

and then used the range equation.

What did you do?

Your reasoning was right for #4. So then, for #9, you have a new initial velocity in both x- and y-directions, and you know the distance the ball has already traveled (or you can get it from what you have done already) => (=> means therefore) you can solve for the distance it still needs to go => yo...

For #12, hold off until you have done #9, some of the reas...
