A ladder placed on a smooth floor slips. If at a given instant the velocity with which the ladder is slipping on the floor is `v_1`, and the velocity of that part of ladder which is touching the wall is `v_1`, then the velocity of the centre of the ladder at that instant is:

A ladder rests on the floor of a room, leaning agains a wall. If the coefficient of static friction between the ladder the floor is mu_(f) and that between ladder and is mu_(w) , what is the minimum angle theta that the ladder can make with the floor if the ladder is not to slip? Assume that the mass of the ladder is distributed uniformly.

A ladder leans against a wall if the ladder Is not to slip which one of the following must be true?

A ladder 3.7 m long is placed against a wall in such a way that the foot of the ladder is 1.2 m away from the wall. Find the height of the wall to which the ladder reaches.

A ladder 3.7m long is placed against a wall in such a way that the foot of the ladder is 1.2m away from the wall.Find the height of the wall to which the ladder reaches.

A ladder is placed along a wall of a house such that its upper end is touching the top of the wall. The foot of the ladder is 2m away from the wall and the ladder is making an angle of 60^@ with the level of the ground. Determine the height of the wall.

A ladder 17 metre long is leaning against the wall. The base of the ladder is pulled away from the wall at a rate of 5m/s. When the base of the ladder is 8 metres from the wall. At what rate, the area of the triangle formed by the ladder, wall, and the floor, is changing?

A ladder is placed against a wall which is inclined at an angle 60^@ with the ground. The foot of the ladder is 4.6m. Away from the wall. Then the length of the ladder is

A ladder of 3.9 m length is laid against a wall. The distance between the foot of the wall and the ladder is 1.5 m. Find the height at which the ladder touches the wall.

A ladder of 4 m length is laid against a wall. The distance between the foot of the wall and the ladder is 1.8 m find the height at which the ladder touches the wall.

A ladder is placed along a wall of a house such that its upper end is touching the top of the wall.The foot of the ladder is 2m away from the wall and the ladder is making an angle of 60o with the level of the ground.Determine the height of the wall.
