In both the cases block & monkey are at the same horizontal level. In both the cases monkey climbs the rope.In case-1 rope remains vertical & in case-2 rope swing during motion. `t_(1)` & `t_(2)` are times taken by monkeys to reach the pulley in case - 1 & case -2 respectively. In both cases, monkey applies the same force on the rope.

A 20 kg monkey has a firm hold on a light rope that passes over a frictionless pulley and is attached to a 20 kg bunch of bananas. The monkey looks upwards , sees the bananas and starts to climb the rope to get them. (a) As the monkey climbs ,do the bananas move up , move down or remain at rest? (b) As the monkey climbs ,does the distance between the monkey and the banana decrease, increase or remain same? (c) The monkey releases her hold on the rope .What happens to the distance between the monkey and the bananas while she is falling ? (d) Before reaching the ground , the monkey grabs the rope to stop her fall. What will happen to bananas ?

A monkey of mass m climbs up to a rope hung over a fixed pulley. The opposite end of the rope is tied to a weight of mass M lying on a horizontal plane. Neglecting the friction, find the acceleration of both the bodies (relative to the plane) and the tension of the rope for the three cases: (i) The monkey does not move with respect to the rope (ii) The monkey moves upwards with respect to the rope with acceleration a. (iii) The monkey moves downwards with respect to the rope, with acceleration a.

In the arrangement shown in the fig. a monkey of mass M keeps itself as well as block A at rest by firmly holding the rope. Rope is massless and the pulley is ideal. Height of the monkey and block A from the floor is h and 2h respectively [h = 2.5 m] (a) The monkey loosens its grip on the rope and slides down to the floor. At what height from the ground is block A at the instant the money hits the ground? (b) Another block of mass equal to that of A is stuck to the block A and the system is released. The monkey decides to keep itself at height h above the ground and it allows the rope to slide through its hand. With what speed will the block strike the ground? (c) In the situation described in (b), the monkey decides to prevent the block from striking the floor. The monkey remains at height h till the block crosses it. At the instant the block is crossing the monkey it begins climbing up the rope. Find the minimum acceleration of the monkey relative to the rope, so that the block is not able to hit the floor. Do you think that a monkey can climb with such an acceleration? ( g = 10ms^(-2) )

In the given circuit, the binary inputs at A and B are both 1 in one case and both 0 in the next case. The respective outputs at Y in these two cases will be:

In fig., a person wants to rise a block lying on the ground to a height h. In both the cases, if the time required is same, then in which case he has to exert more force? Assuem pulleys and strigns light.
