Puzzle:A weightless and perfectly flexible rope is hung over a weightless, frictionless pulley attached to the roof of a building. At one end is a weight which exactly counterbalances a monkey at the other end.
If the monkey begins to climb, what will happen to the weight - will it remain stationary, will it rise or will it fall?
Note: Don't forget to visit us again. Answer to the puzzle will be posted tomorrow.
Solution: As the monkey climbs, the weight will rise by the same amount.

Two cases
ReplyDelete1. If you think that "g" is constant and does not change by distance then nothing will happen as force on both sides remain the same. The weight will stay at its own place.
2. If you take the exact formula
F= G (m1*m2/d^2). Mass of earth and monkey remains same but distance between them increases thus Force decreases and weight on other side has to balance it and thus it will go up also.
Was the monkey being jerked on? If so, it definitely would have reached the climax.
ReplyDeleteTheoretically, they both should be erected and achieve maximum height simultaneously. Although you still need friction to obtain results...
No one can beat Austin in this.
