assume this is a slingshot, so you're pulling at the top of the triangle. g = 6cm, so we've got that s = sqrt(h^2+9).

i want to find an expression for ds/dt in terms of dh/dt and h. I use ds/dt = ds/dh * dh/dt and end up with ds/dt = h/(sqrt(h^2+9)) * dh/dt. i'm given that h rises with a speed of 2 cm/min. now, assuming that the height has reached 11 cm, i find that s is growing by 1.93 cm. does that sound right? sounds like a lot to me desu.
