Thankkkk godddd i was finding derivation of this i watched a ton pf videos but didn't understood then i came across here u teached very nicelyyy thankuuu sir love from shimla😇
In a death well, a person drives a bicycle or a motor cycle on the vertical surface of a large wooden well. The walls of death well are at rest. In death well friction balances the weight of the person while reaction of the wall provides the centripetal force necessary for circular motion. Balancing the vertical forces we get, fmax=μN=μmv^2/r For him not to fall; fmax≥mg⇒μmv^2/r≥mg ⇒v≥√gr/μ ∴ vmin=√gr/μ
@@sharathgoresir I had asked query about v max, and you answered about v min. Kindly go through my query once again, and if possible, let me know the solution for vmax when theta = pi/2.
@@sharathgoresir When I'm putting theta = 90 degrees in the expression for vmax, it is giving an imaginary number. How's that possible. and what does it signify.?

Thank you sir :) you really do explain complex problems in a much more simpler way. Please never stop teaching.
The best physics teacher i have seen in my whole life
Gore Sir .Good Analysis.
The society needs teachers like you ...All the best .
The students will understand effectively.

Thank you sir , very good explanation sir everything is crystal clear now .
You're welcome 🙏
Excellent Explanation Thanks Sir
Keep it up sir 👍
Thank you so much sir
Amazing alhamdulillah i get this
Super sir
Super video sir
Sir when to use sin and cos
Nice teaching sir
Thank you 🙏
am kinda confused.are we not supposed to divide both sides of the equation by tan
No
Sir 👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
Really sir you do sound like Shah Rukh khan😂
Why Nas taken mg
Sir, Suhas Gore sir is your brother???
@@pranavprabhu205 no
@@sharathgoresir o ok
@@sharathgoresir BTW thank you so much sir it was very informative
@@pranavprabhu205 you’re welcome
You sound like shahrukh khan on 1.5x speed😭

Supper class
Thank you 😊
Why frictional force didn't act upward
Frictional force is always parallel to the surface of contact and opposes motion.
What will be vmax when theta = 90 degrees, as happens in the well of death in a circus performance.?
In a death well, a person drives a bicycle or a motor cycle on the vertical surface of a large wooden well. The walls of death well are at rest.
In death well friction balances the weight of the person while reaction of the wall provides the centripetal force necessary for circular motion.
Balancing the vertical forces we get,
fmax=μN=μmv^2/r
For him not to fall;
fmax≥mg⇒μmv^2/r≥mg
⇒v≥√gr/μ
∴
vmin=√gr/μ

@@AK56fire velocity can be anything above v minimum 🙏

@@AK56fire that means you can go with very very very high velocity also (infinite)
Thank you so much!
shouldn't we divide on the both sides???
Yeah. It get cancelled.
Best teaching sir🙂
Thank you very much 🙏
Sir please send annual important questions
I have my exam after 2 hrs
Stay cool. All the best
Thank u sir
His voice is exactly like Shah Rukh Khan😂😂
Eeeeee hee hee 😂😂
