Mr. Cook was painting Arvada West High School, standing on top of a 25]foot ladder. Why? We will never

know. However, he was horrified to find the ladder being pulled away by the same notorious student that

threw a snowball at Mrs. Evans. The base of the ladder was moving from the school at a constant rate of 2

feet per second.

8) At what rate was the top of the ladder carrying him down toward the ground when the base of the ladder

was 17 feet away from AWest?

draw the triangle.

b^2+h^2=25^2

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

solve for h (sqrt (25^2-b^2)

you know db/dt, b, h, solve for dh/dt
