Tom is climbing a 3.0-m-long ladder that leans against a vertical wall, contacting the wall 2.2 mabove the ground. His weight of 680 N is a vector pointing vertically downward. (Weight is measured in newtons, abbreviated N.)
What is the magnitude of the component of Tom's weight perpendicular to the ladder?

A ladder 23 feet long leans against a wall and the foot of the ladder is sliding away at a constant rate of 3 feet/sec. Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of ?/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the...
