Engineering Science N2 Dynamics: Exam Revision Part 1

[@SWreacts]

Thanks so much. I passed my exams because of your videos

[@DineoDlamini-qv6pn]

Thank you so much I got 80% on my test 1❤❤🥳

[@nelsonpohotona4851]

May I DM you on Instagram ? I would like to ask a few questions regarding science

[@SindiDladla-zh7xg]

I'm very happy with your explanations. thank you sir

[@ayandaambermogoba9712]

hey quick question at the last question can i ask why you used the x-axis with zero when the time says 20 and 25 respectfully

[@roipop]

t=20s has a v=80 m/s and t=25s has v=0 m/s from the table. Hence the graph ends at 0 on x-axis. I hope this answers your question.

[@sandilewesleigh8602]

Hy sorry to intervene, weren't you supposed to use the last 5 seconds by subtracting the first 20 seconds from the 25 seconds? Please explain why not if I'm wrong

[@ayandaambermogoba9712]

No it doesn’t cause on both coordinates you put zero when only one coordinate was supposed to have a zero

[@deni.b4577]

@@roipop meaning the coordinates are (20,80) (25,0) right? 🤔

[@nqubekomthethwa]

It's supposed to be (20 ; 80) because at t=20 the velocity is 80,you still used 80 but the way you used it,you said at 80m/s the time was 0s,which it was not.

[@nokulungamasina]

hey,quick question regarding 1.3.3 why did you calculate the displacement before the 20 sec instead of after the 20sec?

[@inoh4194]

He made a mistake

[@belindamalope]

Also 1.3.2

[@belindamalope]

What paper is this cause I wanna see the memo

[@tanakamuchemwa]

Good teaching

[@roipop]

Thanks and welcome

[@m3ch1n39]

thank you very much

[@Sheila_Mathabo]

The Displacement said "after the first 20 seconds"
Are we not supposed to focus on the last 20 which is 1/2b×h "thr last shape"

[@nwamxenguref8487]

I'm also confused

[@NtokozoInganeYakwaLuthuliLuthu]

Initial time for last 5 sec is wrong

[@thabochauke4052]

Incorrect.

[@samanthakaviya7712]

Thank you Sir

[@roipop]

Most welcome

[@ColeLarey-oz3lk]

Hi sir , any way for me to purchase 2023 engineering science n2 November memo?

[@kalonjiguy6009]

hi , the height is not 60 but 40

[@christinahmoropodi3303]

Still cant work this out

[@portiazanelemonkwe1739]
