Tank you so much sir, ❤❤❤

[@jamesrowell9306]

Do you have a solution for if the wall isnt smooth?

[@sarwagyaacharya419]

Thank you so much.

[@jaswanthreddy-jk1bq]

it's a great explaination sir!

[@dr.piercesphysicsmath9071]

Awesome! Thank you.

Thank you sir....

[@dr.piercesphysicsmath9071]

You are welcome! I hope it was useful. It's fun to see some people learning from these video clips.

I have a problem, why the wall does not provide vertical upward reaction (friction) in this case?

[@dr.piercesphysicsmath9071]

Simply because of the design of the prompt; the wall was assumed to be slippery. One could also define a friction coefficient for the wall and then it would need to be taken into consideration, as you suggest.
