15:35 Let's say you make down as positive, the vi of 8.1 will be -8.1 and acceleration of -9.8 will be 9.8. But if you do that, you don't get the same vf of 6.78306... So what do you do?
Hi Kevin. Hope you well. I would love to know what software you use for your whiteboard. I will be tutoring maths online with learners so plz respond if you can🙏🏾
@kevinmathscience for question 4.2.2) iii I used the quadratic formula and both my time values were positive. How do we know what to do in this situation? It would be a waste of time to redo the question using a different equation of motion .

I actually did this the day before yesterday n i dont mean to brag but i aced it all.........VPM is not bad at all🤞🏿😅
Good for u 🎉🎉🎉
Re a go lebogisha
yes wena😂
Hi Kevin, why did you make the acceleration negative if up is positive? 15:08
gravity is downwards
Acceleration is always acting downwards, if up is positive accl is negative. If down is taken as positive, acceleration too is positive.
Hey Kev, Just a question. for 4.2.2- ii) Wouldn't the max height be the 7.35 + 4(because that is the height of the balcony) = 11.35?
