Why would he want to climb upward to get out of a building? Shouldn't he lower himself down from the building?brycenrg said:Homework Statement
A 75 kg thief wants to escape a building. He has a rope that supports 58kg how can he escape?
Homework Equations
f=ma
The Attempt at a Solution
75kg*g = W
58kg*g = T
T - W = 75kg*a
a = (t-w)/m
If he applies a acceleration upwards at 2.2 m/s^2 he would survive.
When i do the calculation I get a negative number, which would mean he would be applying a acceleration downwards which doesn't make sense. Why is that?
In my equation T is positive
That makes sense he has to accell downwards to go. But what it means is if he accels downwards more that 2.2 then the rope wouldn't support him right?Mark44 said:Why would he want to climb upward to get out of a building? Shouldn't he lower himself down from the building?
I think you are confused. If he was just hanging from the rope, with no accleration, the rope would break, right? If he slid down the rope, just barely hanging onto it (which would burn his hands), he would be acclerating at just under ##9.8 \frac m {sec^2}##. Would the rope break then?brycenrg said:That makes sense he has to accell downwards to go. But what it means is if he accels downwards more that 2.2 then the rope wouldn't support him right?
I am, I want to say if he used friction to slow him down to just = to T and under that force he would be ok. Which is under 2.2m/s^2.Mark44 said:I think you are confused.

Yes, it doesn't make sense, and that isn't what I was saying, either.brycenrg said:I am, I want to say if he used friction to slow him down to just = to T and under that force he would be ok. Which is under 2.2m/s^2.
But it seems like your saying he has to be going faster than gravity, which doesn't make sense to me
The moral dilemma surrounding helping a thief escape is whether it is right to assist someone in evading punishment for their actions, especially if those actions were illegal or harmful to others.
The potential consequences of helping a thief escape include facing criminal charges yourself, being complicit in the thief's future crimes, and damaging your own moral integrity.
This is a highly debated question and opinions may vary. Some may argue that it is never justified to assist someone in avoiding the consequences of their actions, while others may argue that it depends on the circumstances and the severity of the crime committed.
A scientist should consider their personal ethics, the potential consequences of their actions, and the impact it may have on their career and reputation. They should also consider the potential harm that could be caused by the thief in the future if they are allowed to escape punishment.
A scientist should carefully weigh the pros and cons, seek advice from ethical experts or colleagues, and consider the potential implications of their actions on themselves and others. It may also be helpful to consider alternative methods of helping the thief, such as counseling or rehabilitation, rather than aiding in their escape.
