Exactly why i switched to the second method! μ being more than 5 is mad!!
how could U exceed 1 lol dude.
Exceeding 1 is possible for sure. Firstly, in real life there are materials with a coefficient of friction greater than 1. Secondly, there was a m18 question that told us to prove that the coefficient of friction is 4/3. But 5 is too high, thus that method is incorrect
didn't know that, thanks. i tried the right method i guess. P +- F -mgsintheta = 0
it'll be 41-43 this time i guess so.
I am expecting 38-40 as thresholds this time
it was surely easier than that, and who knows better than u.
Haha, it was easy for me, but others found it challenging. So this is based on how everyone in my batch responded, not just me
alright then, let's hope it is less.
this is not an occasion to joke around you know
Probably this paper was the easiest among entire m1 papers i have ever encountered tbh...
people got common wrong answers, which means it was tricky to some extent.
Yeah common wrong answers show that there was a trend of difficult questions, so you might expect thresholds to be low. Maybe lower than last year's.
Holy shit, exact same answers.
i remember all the paper, if you need it.
do you remember the values for the first question? like what was the power and velocity?
A runner of mass 80kg increases his speed from 4ms^-1 to 5.5ms^1 against a restistive force P over a distance of 60m. Total work done is 1200J. Find the value of P
