Document Summary
Q: a homeowner sets up an 18ft long ladder against the side of a house. The ladder begins to slide down the wall. One foot before the top of the ladder hits the ground, it"s falling at a rate of 20ft/s. At this moment, how fast is the foot of the ladder moving away from the wall? h is changing. is changing. length, 18ft is unchanging. r h t a y b. You"re told that the ladder is falling at a rate of 20ft/s. Going down is negative, so h is the distance from the top of the ladder to the bottom of the wall. is the distance from the base of the ladder to the wall. ad = ? ddtn. Label it with any unchanging measurements assigning variables to changing measurements. List all given rates the rate you"re asked to figure out. Write these rates as derivatives with respect to time .
