A uniform rope of mass `m` per unit length, hangs vertically from a support so that the lower end just touches the table top shown in figure. If it is released, show that at the time a length `y` of the rope has fallen, the force on the table is equivalent to the weight of the length `3y` of the rope.

A very flexible chain of length L and mass M is vertically suspended with its lower end just touching the table. If it is released so that each link strikes the table and comes to rest, what force the chain will exert on table at the moment 'y 'part of length falls on table ?

A uniform rope of mass 6 kg and length 6 m hangs vertically from a rigid support. A block of mass 2 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.075 m is produced at the lower end of the rope. The wavelength of the pulse when it reaches the top of the rope is K cm where K is

A uniform rope of length 12 m amd mass 6 kg hangs vertically from a rigid support.A block of mass 2 kg is attached to the free end of the rope.A transverse pulse of wave length 0.06m is produced at the lower end of the rope.What is the wavelength of the pulse when it reaches the top of the rope?

A uniform rope of length 10 m and mass 15 kg hangs vertically from a rigid support. A block of mass 5 kg is attached to the free end of the rope. A transverse pulse of wavelength 0.08 m is produced at the lower end of the 3 rope. The wavelength of the pulse when it reaches the top of the rope will be-
