A man of 80 kg fastns a rope to a mass of 120kg, and passes the rope over a smooth pulley. In order to raise it up he climbs the riope with acceleration (3g)/2 relative to the rope. Calculate the tension in the rope in N. (Take g=10m//s^(2) )

To raise a weight which is half as much again as his weight a man fastens a rope to it and passes over a smooth pulley, he then climbs up the rope with an acceleration (6g)/(7) relative to the rope. Show that the weight rises with acceleration (8)/(7) , and find the tension of the rope.

    A boy of mass 40kg climbs up a rope with an acceleration of 1.2ms^(-2) .What is the tension in the rope?

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

    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.
