How was your maths 42 M1

I feel the same browski, but the other method seems legit to me too. The only reason it puts me off is because the value for coefficient of friction is too large. I know the coefficient of friction can be more than 1 but not as high as 5!

Exactly why i switched to the second method! μ being more than 5 is mad!!

how could U exceed 1 lol dude.

 

[hellodjfos;s'ff]

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

thresold never exceeded more than 45 i guess so? for m1 paper in its entire history.

it'll be 41-43 this time i guess so.

 

[hellodjfos;s'ff]

I am expecting 38-40 as thresholds this time

it was surely easier than that, and who knows better than u.

 

[hellodjfos;s'ff]

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

 

[muaz_ali]

alright then, let's hope it is less.

 

[muaz_ali]

why idk i feel thresold will hit 50 for A and 48 for a B. just guessing you. You never know.

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.

 

[hellodjfos;s'ff]

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.

It was very nice.
Q1 10.5
Q2 2060kw
Q3 41.1 and 3.92
Q4 19 and 312
Q5 0.577
Q6 30 and 20m
Q7 3 and 4.8, 2.1
I got these and these are right i confirmed.

Holy shit, exact same answers.

 

[muaz_ali]

Holy shit, exact same answers.

congrats!

If anyone gets hold of the mechanics paper, please do post it. I need to check it with my teacher.

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

bingo!
