A 100kg man is going up a leaning 20kg ladder. The ladder is set at 55 degrees. The floor and ladder have a coefficient of friction of .4. The wall is frictionless. How far up the 5m ladder can he safely climb?

What theta would allow the man to get all the way to the top?

A 25 kg uniform ladder is leaning at a 60o angle against a frictionless wall. It is a slick day—the coefficient of static friction between the floor and the ladder’s base is only 0.4. a. How far up the ladder (in terms of the fraction of the ladder’s length) can a 75 kg person climb before the ladder begins to slip? b. What is the minimum angle the ladder needs to allow the person to climb to the very top...

A 5.5 m long ladder with a mass of 10.0 kg is leaning against a wall at a dangerously large angle of 35° (between the ladder and the wall). The coefficient of static friction between the base of the ladder and the floor is 0.50 and the top of the ladder has wheels so there is negligible friction between the ladder and the wall. How far up along the ladder can a 65.0 kg painter climb before the ladder slips?...

A 6 m long, uniform ladder leans against a frictionless wall and makes an angle of 58 ◦ with the floor. The ladder has a mass 26.4 kg. A 68.64 kg man climbs 82% of the way to the top of the ladder when it slips and falls to the floor. What is the coefficient of static friction between the ladder and the floor?

On a Romanian infomercial the 75.0 kg presenter attempts to climb a 2.25 m long ladder with a mass of 5.00 kg at an angle of 70.0°. The ladder is held up by two other presenters that act as a frictionless wall. The man on the ladder reaches a height of 1.80 m when the ladder slips. a) Solve for the normal forces on the ladder. b) Solve for the coefficient of friction between the ladder and the floor.

A ladder of length 15.0 m and of mass 45.0kg is leaning against a frictionless building wall. An85.0-kg person standing on the ladder, 1.00 m from its top end, asks his friend to stand on one of the lower rungs to prevent the ladder from slipping. If the friend’s mass is 65.0 kg, where should he stand to keep the entire system in equilibrium? The coefficient of friction between the ladder and the ground is 0.300, and the angle that...
