A 10m long ladder leaning on a wall reaches the height of 5m on the wall. Then, the ladder makes a `30^(@)` angle with the wall.

A ladder makes an angle of 60^(@) with the ground, when placed leaning on a wall. If the foot of the ladder is 8m away from the wall, then the length of the ladder is ………m

A ladder rests against a wall at an inclination alpha to the horizontal. Its foot is pulled away from the wall through a distance p so that its upper end slides a distance q down the wall and then the ladder makes an angle beta to the horizontal. Show that (p)/(q)= (cos beta -cos alpha)/(sin alpha- sin beta)

A ladder 20 feet long is leaning against a wall. The bottom of the ladder is 16 feet away from the wall. If the upper end of the ladder slide along wall is lambda times the lower end of the ladder pull along the ground. Find the value of lambda .

A ladder 10 m long reaches a window 8 m above the ground. Find the distance of the foot of the ladder from base of the wall.

A ladder 5 cm long is leaning against a wall. The bottom of the ladder is pulled along the ground, away from the wall, at the rate of 2cm/s. How fast is its height on the wall decreasing when the foot of the ladder is 4 cm away from the wall ?

A ladder rests against a frictionless vertical wall, with its upper end 6 m above the ground and the lower end 4 m away from the wall. The weight of the ladder is 500 N and its CG at 1//3^(rd) distance from the lower end. Wall's reaction will be (in newton)

One end of a light spring of natural length 4m and spring constant 170 N/m is fixed on a rigid wall and the other is fixed to a smooth ring of mass (1)/(2) kg which can slide without friction in a verical rod fixed at a distance 4 m from the wall. Initially the spring makes an angle of 37^(@) with the horizontal as shown in figure. When the system is released from rest, find the speed of the ring when the spring becomes horizontal.

On end of a light spring of natural length d and spring constant k is fixed on a rigid wall and the other is attached to a smooth ring of mass m which can slide without friction on a vertical rod fixed at a distance d from the wall. Initially the spring makes an angle of 37^@ with the horizontal. as shown in figure. When the system is released from rest, find the speed of the ring when the spring becomes horizontal. (sin 37^@=3/5) .

A ladder 5m long is leaning against a wall. The foot of the ladder is pulled out along the ground away from from the wall at a rate of 2 m//s . How fast is the height of ladder on the decreasing at the instant when the foot of the ladder is 4 m away from the wall?

A ladder, 5 meter long, standing on a horizontal floor, leans against a vertical wall. If the top of the ladder slides downwards at the rate of 10 cm/sec, then the rate at which the angle between the floor and the ladder is decreasing when lower end of ladder is 2 metres from the wall is ............
