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

`1.256`m

`2.532`m

`3.513`m

`2.125`m

Text Solution

Verified by Experts

The correct Answer is:

Mass of ladder acts at 2.5 cm Mass of man acts at 2m
`y = (m_(1)y_(1)+m_(2)y_(2))/(m_(1)+m_(2))`

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 3.25 m and weight 250 N is placed against a smooth vertical wall with its lower end 1.25 m from the wall. If coefficient of friction between the ladder and the floor is 0.3, then, find the frictional force acting on the ladder at the point of contact between ladder and floor.

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?

A ladder 25m long reaches a window of a building 20m above the ground.Determine the distance of the foot of the ladder from the building.

a ladder of length L=12 m and mass m = 45 kg leans against a slick wall (that is, there is no friction between the ladder and the wall). The ladder's upper end is at height h = 9.3 m above the pavement on which the lower end is supported (the pavement is not frictionless). The ladder's center of mass is L//3 from the lower end, along the length of the ladder. A firefighter of mass M = 72 kg climbs the ladder until her center of mass is L//2 from the lower end. What then are the magnitudes of the forces on the ladder from the wall and the pavement?
