He writes opposite as you would, just so that he can record it in a friggin cool way and still explain it Damm his brain co ordination Big fan sirr 🙏🏼🙏🏼🙏🏼🙏🏼
a stone of mass 5kg falls from the top of a cliff 50m high and buries 1m in deep in sand.find average resistant offered by sand (the answer in the book is 2450N) and if i use the equation Fres= mg(1+h/x) the answer i get is 2499N COULD YOU EXPLAIN THIS PLEASE
It is always a treat to learn physics from someone who visibly loves it so much. Thank you for the video, Dr. A!

Big fan sirr 🙏🏼🙏🏼🙏🏼🙏🏼

Just how do you manage to write backwards so quickly
I fake it.

you makes physics easy
You have great videos!

vf^2 = vi^2 + 2gh just before hitting the ground, then Vf^2= vi^2 +2ad as it penetrated the sand to get acceleration, then F =ma, you will get 2499N
Your explanation is so easy thanks alot
Thank you!!!!!!
You are welcome.
Cheers,
Dr. A
Good job
How do you write that way sir?
This video explains what exactly is going on:

He sounds a little like sheldon cooper lol how fitting
Awesome, thanks for the comment.
Keep up with the physics!
Cheers,
