**bobpursley**, Monday, December 8, 2008 at 4:40pmUsing Pythagorean theorm,

length^2=b^2+ h^2

where b is the base length, and h is the height.

Taking the derivative..

0=2b db/dt + 2h dh/dt

you are given db/dt, solve for dh/dt

For the second part, you will have to find b and h at 30 sec. b will be .40*30, solve for h, and again, you have it.
