The mass of a uniform ladder of length `5m` is `20kg`. A person of mass `60kg` stand on the ladder at a height of `2m` from the bottom. The position of centre of mass of the ladder and man from the bottom is

The mass of a uniform ladder of length 5 m is 20 kg. A person of mass 60 kg stands on the ladder at a height of 2 m from the bottom. The position of centre of mass of the ladder and man from the bottom nearly is

The mass of a uniform ladder of length 6m is 20kg. A mass 60kg is placed on the ladder at a height of 2m from the bottom. The position of centre of mass from the bottom is

The mass of an uniform ladder of length l increases uniformly from one end A to the other end B, find the position of the centre of mass from end A.

A uniform ladder of length L and mass m_(1) rests against a frictionless wall. The ladder makes an angle theta with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when a firefighter of mass m_(2) is a distance x from the bottom. (b) If the ladder is just on the verge of slipping when the firefighter is a distance d from the bottom, what is the coefficient of static friction between ladder and ground?
