A man of mass m climbs a rope of length L suspended below a balloon of mass M. The balloon is stationary with respect to ground. If the man begins to climb up the rope at a speed v_("rel") . (relative to rope) in what direction and with what speed (relative to gound) with the balloon move ?

A man of mass m climbs to a rope ladder suspended below a balloon of mass M . The balloon is stationary with respect to the ground. (a) If the man begins to climb the ladder at speed v (with respect to the ladder), in what direction and with what speed (with respect to the ground) will the balloon move? (b) What is the state of the motion after the man stops climbing?

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) )

A rope thrown over a pulley has a ladder with a man of mass m on one of its ends and a counter balancing mass M on its other end. The man climbs with a velocity v_r relative to ladder. Ignoring the masses of the pulley and the rope as well as the friction on the pulley axis, the velocity of the centre of mass of this system is:

A massless rope of length 100 m and of breaking strength 108 N is hanging from the branch of a tree. A monkey of mass 6 kg is trying to climb up the rope starting from rest. Find the shortes time in which monkey can climb the full length of rope with uniform acceleration so that the string will not break ?

A mass of 10 kg is suspended vertically by a rope from the roof. When a horizontal force is applied on the rope at some point, the rope deviated at an angle of 45^(@) at the roof point. If the suspended mass is at equilibrium, the magnitude of the force applied is (g =10 ms^(-2) )
