Homework Statement A ladder 10 ft long rests against a vertical wall. If the bottom of the ladder slides away from the wall at a rate of 1.3 ft/s, how fast is the angle between the ladder and the ground changing when the bottom of the ladder is 6 ft from the wall? Evaluate your answer...

Ah, Thank You so much for this. I was able to nail down all the rest of my problems like this. PROPS! -Ryan

Can you please e plain how you worked that out ? Thank You, Ryan

Ok I did get the avg acceleration for the first 20 seconds done by getting the slope which turned out to be right, evil online submission system >.> As far as the rectangle.. uh how is it 1.5 * 20 seconds when it clearly levels off at 2(m/s) for the interval between 20 and 40 seconds...

Homework Statement The green line is the graph. I added in the redlines to form the shapes to find the total distance X traveled by the particle. I know I can figure out that the one side of the rectangle is 40m due to the fact that it is going 2m/s for 20 seconds at that part. The thing that...
