This is the problem:
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.
In my notes, I have a similar type of problem with the work shown:
But I still can't figure it out, and more specifically I don't know if 4 ft/sec is dy/dt or dx/dt, and how I'm supposed to use t=s.
Help please? This is due in a few hours so I would appreciate a fast response.
