A ladder is at rest with its upper end against a wall and the lower end on the ground. Is the ladder more likely to slip, when a man stands on it at the bottom or a the top? Give reason.

A ladder is kept at rest with is upper end against a wall and the lower end on the ground. The ladder is more like to slip when a mass stands on it at the top than at the bottom. Why ?

A ladder of length 17m rests with one end agains a vertical wall and the other on the vessel ground. If the lower end slips away at the rate of 1ms^(-1) , then when it is 8m away from the wall, its upper end is coming down at the rate of

A ladder of length L is slipping with its ends against a vertical wall and a horizontal floor. At a certain moment, the speed of the end in contact with the horizontal floor is v and the ladder makes an angle theta=30^@ with horizontal. Then, the speed of the ladder's centre of mass must be
