Homework Help: Help with related rates problem

  1. Nov 10, 2011 #1
    1. The problem statement, all variables and given/known data

    A 16-ft ladder is sliding down a wall at a rate of 4 ft/sec. Find the velocity of the top of the ladder at t=s if the bottom is 5ft from the wall at t=0.

    2. Relevant equations

    It's a related rates problem.
    Not sure how I'm supposed to incorporate t=s into the problem, or if I'm supposed to solve for dx/dt or dy/dt.
    Or if I'm even on the right track.

    3. The attempt at a solution

    Thought I would add, this is a similar problem that was in my notes, but there are differences between the two problems such as the direction the rate of the ladder is sliding and I have to find it at t=s.

    This is due in a few hours I hope I get a response by then.
