A 14 foot ladder is leaning against a building If the bottom

A 14 foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 3 ft/sec, how fast is the top of the ladder moving down when the foot of the ladder is 5 feet from the wall?
answer in ft/sec, rounded to the nearest thousandth

velocity along the rod will remain same at both ens thus we have 3*5/14=v*13.07/14 v=1.147 ft/sec
