As shown in figure a monkey of 20g mass is holding a light rope that passes over a frictionless pulley. A bunch of bananas of the same mass is tied to the other end of rope. Inorder to get access to the bunch the monkey starts climbing the rope. The distance between the monkey and the bananas is

A 12 kg monkey climbs a light rope as shown in figure. The rope passes over a pulley and is attached to a 16 kg bunch of bananas. Mass and friction in the pulley are negligible so that the pulley's only effect is to reverse the direction of the rope. What is the maximum acceleration the monkey can have without lifting the bananas?

A monkey of mass 40 kg climbs on a rope as shown in figure which can stand a maximum tension of 600 N. In which of the following cases will the rope break the monkey. (a) Climbs up with an acceleration of 6 ms^(2) . (b)Climbs down with an acceleration of 4 ms^(2) . (c )Climbs up with a uniform speed of 5 ms^(1) . (d)Falls down the rope nearly freely under gravity ? (Ignore the mass of 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.

Two masses 8 kg and 12 kg are connected at the two ends of a light inextensible string that goes over a frictionless pulley. Find the acceleration of the masses, and the tension in the string when the masses are released.

A trolley is being pulled up an incline plane by a man sitting on it ( as shown in figure). He applies a force of 250 N. If the combined mass of the man and trolley is 100 kg, the acceleration of the trolley will be [sin 15^(@)=0.26]

The monkey B shown in fig. is holding on to the tall of the monkey A which is climbing up a rope. The masses of the monkeys A and B are 5 kg and 2kg respectively. If A can tolerate a tension of 30N in its tall, what force should it apply on the rope in order to carry the monkey B with it ? (Take g=10 ms^(-2) )

Two blocks of masses 6 kg and 4 kg are connected with rope of mass 2 kg are resting on a frictionless floor as shown in the following figure: If a constant force of 60N is applied to 6 kg block then the tension in the rope at points A,B and C are respectively given by :
