[tejaswinichandane]

It was a very helpful video. The analogies explained through diagrams really helped. Thank you!

Sir also for 27, what happens if intensity is increased? I just want to confirm smthing..thanks!

[marc]

Sir would you agree that question 16 is badly worded, since each brake applied is 300,

[moteekhesavraj]

Sir the formula for number 25 is Fs(V/(V + Vs))

[marc]

For 34, why dont sir use P=V^2/R to calculate the ratio instead?

[Parthanaux_H]

at time 23:25 . this analogy is wrong and may backfire. you first correctly associated a positive and a negative value to the directions, and also correctly subtracted the momentums of the trolleys. if you had kept the negative sign in your answer when you got the velocity, you could have matched the negative sign with the left direction, and hence known that that the velocity of the combined trolleys will be to the left.

Bro it was Train directly moves away but why did u towards . HELP FULL VIDEO THANKS

[zenpainn]

thank you so much for this, could you explain 26 again?

[lukemwendwa]

could you please do recent papers eg 2022, 2023
