Forever the best teacher

[@kevinmathscience]

I appreciate this!!

[@Carine.Bukasa-jp8lo]

Thank you mr Kevin.🙏

In the combined method, I get the answer -928,2709915. I made sure to use brackets between the (20 and the -2) before multiplying by 5

try again. you did something wrong

[@coletaljaard2227]

You are amazing. Thank you Kindly🙏

20:05 Sir i have a question 🙋 ..My teacher said that when the object is moving downwards we use Cos(180⁰) when we are calculating Net Work done by Applied Force,but you said we use cos(0⁰)now i'm confused

[@motlalepulantlaly3859]

Sir I got 444.91 j for work of parallel gravitational not the one you got and my Total net work is 485.4J not 530j 🥺💔

[@biac_torrid]

Hi sir. Why do we only use the parallel gravitational force and not the perpendicular gravitational force when calculating work in this situation? Also sir is there another way to do it without breaking Fg into 2 components?

go back to the previous video 3/21 he explains why 😘
