a massless rope is strung over a frictionless pulley. A monkey holds onto the rope, and a mirror having the same wieght as the monkey, is attached on the other side of the rope at the monkeys level.
(a) climbing up the rope
(b) climbing down the rope
(c) releasing the rope
explain...
for all the answers i put no. because the weight is the same, so there is same amount of tension and accleration...but the accleration is just in same magnitude but opposite direction. am i right? rather, is the explanation i provided right?

lol...oops the questions is can the monkey get away from the image it sees in the mirror by....

You're right. Except technically the amount of tension can change (whether the monkey moves up or down) and the acceleration of the monkey and mirror are in the SAME direction (that's why he can't escape).

No, your explanation is not right.
The point is what happens to the IMAGE in the mirror, not what happens to the mirror itself. Climbing the rope, releasing the rope, all those things would raise or lower the mirror, but what would happen to the image? Try getting yourself a mirror. Hold it parallel to the wall, look in it, and see what happens when you raise the mirror up an inch or down an inch.
