A ladder 20 ft long has one end on the ground and the other end in contact with a vertical wall. The lower end slips along the ground. If the lower end of the ladder is 16 t away from the wall, upper end is moving lamda time as fast as the lower end, then lamda is

The one end of a 20 m long ladder is on the floor and the other end is in the contact of vertical wall. Its lower end slides on the floor. Show that the rate of sliding of the upper end is 4/3 times the rate of sliding the lower end when the lower end is 16 m away from the wall.

A ladder of length 20 feet rests against a smooth vertical wall. The lowerend, which is on a smooth horizontal floor is moving away from the wall at the rate of 4 feet/sec. If the lower end is 12 feet away from the wall, then the rate at which the upper end move, is
