In order to raise a mass of 100 kg, a man of mass 60 kg fastens a rope to it and passes the rope over a smooth pulley. He climbs the rope with acceleration `5g//4` relative to the rope. The tension in the rope is (take `g=10 ms^(-2)`)

Tension in the rope at the rigid support is (g=10m//s^(2))

A boy of mass 40 kg climbs up a rope with an acceleration of 2 ms^(-2) . What is the tension in the rope ?

Tow men of masses m_(1)and m_(2) hold on the opposite ends of a rope passing over a frictionless pulley. The men m_(1) climbs up the pore with an acceleration of 1.2m//s^(2) relative to the rope. The mann m_(2) climbs up the rope with an acceleration of 2m//s^(2) relative to the rope. Find the tension in the rope if m_(1)40 kg and m_(2)=60kg. Also find the time after the time after which they will be at same horizontal level if they start from rest and are initially separted by 5 m.

A man of mass m is suspended in air by holding the rope of a ballon of mass M . As the man climbs up the rope, the ballon

A uniform rope of mass m hangs freely from a ceiling. A bird of mass M climbs up the rope with an acceleration a. The force exerted by the rope on the ceiling is

A body of mass 60 kg is holding a vertical rope . The rope can break when a mass of 75 kg is suspended from it. The maximum acceleration with which the boy can climb the rope without breaking it is : ( g = 10 m//s^(2))

Two mass m_(1) and m_(2) are attached to a flexible inextensible massless rope, which passes over a frictionless and massless pully. Find the accelerations of the masses and tension in the rope.
