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 5.00 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.40 m from the wall, and the top of the ladder is 4.39 m above the floor. The spaceship moves past the Earth with a speed of 0.86c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor, as seen by an...

A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?

A ladder 5.90 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.60 m from the wall, and the top of the ladder is 5.30 m above the floor. The spaceship moves past the Earth with a speed of 0.92c in a direction parallel to the floor of the ship. What is the length of the ladder as seen by an observer on...
