Re: Machines B/C
Ohhh your answers make so much more sense. Yeah I do know trig, but I wasn't thinking very hard
I made way too many silly mistakes
I'll try to think of a problem soon. This was a great one!

For 2 points, I will revive this thread (oh wait, I'm dead, nvm). Current Assassinator game, for context
More hand-drawn diagrams! The block in this scenario has a mass of 200.0kg. The coefficient of kinetic friction between the cast iron block and oak wood floor (those were easy to look up, okay?) is 0.485. Assume gravity is9.81m/s^2. Each graph paper square on this diagram represents one square meter.

Answer all of the following with appropriate significant figures, if applicable.
Edit 2: Parts C&D are impossible

Answer all of the following with appropriate significant figures, if applicable.
- What is the system formed by pulleys 2-5 known as?
- What is the IMA of this system?
- What is the AMA of this system?
- What is the efficiency of this system?
- If the block is dragged two squares right (in the imperfect, not ideal system), how much work was done?

Re: Machines B/C
It's okay small stick person. I care about how much effort it takes you to drag a cast iron block that's as tall as you with a wack giant pulley system. (I'll wait a few more days and then assume I've killed the marathon and post a new question).Godspeed wrote: ↑Sat Sep 26, 2020 9:39 pm(When nobody responds because it's too hard)RiverWalker88 wrote: ↑Sat Sep 26, 2020 4:11 pm For 2 points, I will revive this thread (oh wait, I'm dead, nvm).

Thanks, Umaroth for pointing out that you can't calculate the AMA of the system, thus making parts c and d impossible.RiverWalker88 wrote: ↑Sat Sep 26, 2020 4:11 pm For 2 points, I will revive this thread (oh wait, I'm dead, nvm). Current Assassinator game, for context
