I'm upgrading Physics and Maths😀 Ever since I joined this family I'm learning alot I'm never leaving😀😢!! Thank You So Much Mr Nkosi for taking your time to help us out!! God Bless You🙏🙏
Hi there🥰I also initially used the 20m.s however I realised that if you read 4.2 again they ask for the combined velocity after the roller has picked up the boy which is the 17m.s up the incline, before coming to a stop. However the 20 m.s is the rollers velocity before moving up the incline. So you don’t use it.
So in 4.3 they ask for the distance uppppp the incline. So your initial velocity up the incline will be the 17m.s you got from 4.2 and your final velocity up the incline will be 0m.s as the roller and the boy come to a stop or at rest. I hope this helps🫶🏽❤

You are welcome 😊
For anyone wondering you could have used the Work-Energy principle, Wnet=Change in kinetic energy.
hi sir when doing the trig ratios why did you put 17. for the height and not 14.
Mr Nkosi please do a video on emission and absorption spectra
This will help for the Friday paper
Most definitely
I'm writing physics tomorrow so wish me luck and this has helped me
I know you will ace it
Me too dude😳
@@simanyesobekwa1398 I'm grateful 😊
@@simanyesobekwa1398 how was it bro
@@malq-savage6418 I am still to write it tomorrow morning
is our distance not 41,98
Is it?
Hi sir ,for question 4.3 it shows that 17.74 ÷sin25 is equal to 41.976 ,so I'm not sure if yours is correct or mine Is wrong
Please check if your calculator is in Degrees and not Radians
Sir accidentally wrote 17.74 on paper but wrote 14.74 on the calculator!!
@zubaidahjohnny9357 I don't know if this is any help for you at this time but yours is correct.
YOURE TOOOOOOOOOOOOOOOOO AMAZING
The genuineness behind this comment... Oh my goodness! Thank you so much
Sir why are we using 17 m.s as our velocity instead of 20 m.s in question 4.3
Hi there🥰I also initially used the 20m.s however I realised that if you read 4.2 again they ask for the combined velocity after the roller has picked up the boy which is the 17m.s up the incline, before coming to a stop.

Helpful 🎉🎉🎉
Malome where can I get this previous question papers
I only had a hard copy…
We wrote about this question in June. Yeah, it hit most of us at school 😅
You will show it real flames this time around.
U're the best sir
Thank you
Thank you sir.
You're welcome, 😊
Awesome
sir why did you substitute 17 m.s-1 on the velocity for MEbefore not 20 m.s-1 ? wasn't 17 supposed to be for MEfinal
On the ramp, he started at 17m.s-1
