Boat Crossing River

You want your boat to go straight across the moving river. What angle should you point the boat?

Phew!!! A video that finally explains this boat crossing river question. I had to go through so many unhelpful videos to find this one. Thanks a million.

[hi]

dude, explained something better in 8 minutes than my teacher did in 1 week 💀

Dear Mr. Anderson,
Thank you so much for this video. It really made the concept of dividing up problems into vectors clear to me. I am so grateful.

Thanks so much!

Just here to say thank you for uploading this. I see way too many videos that make this simple problem a lot more complicated. Thank you.

Last time I sank my canoe crossing a vicious current I was yelling "but the VRE is less than..."

[yuhankim]

I leave comments on youtube maybe every once in like a year. You explain 20x better than my professor

[manuboker]

Wonderful lecturer that makes physics fun and understandable !!!

Thanks you sir! Atast I learnt it here! Huge respect from India 🇮🇳

[goldenexperincerequiem]

Hello sir You are a life saviour I am from foreign country I didn't actually understood from my mother-language and I was checking everything to understand this subject and I found you so thanks a lot sir now I can pass the exam hahah Have a good day/evening sir

[DT-znem]

Wow sir I really understood the problem so well I am able to do my problems in my textbook now thank-you!!! 🇮🇳🇮🇳🇮🇳

[sathwikakota]

I am from India . u r explanation of next level

Hello sir thankyou for your video but I have a question, what if the maximum speed of the boat is smaller than the velocity of the water flow and we have to find the angle theta and the speed of the boat relative to earth in which the boat has minimum horizontal displacement

[chigo_e]

Thank youuuu!!!!
Short and straight to the point...

[EMMANUELBOAFO-zzlw]

I don't understand why he used sin for the horizontal component

[abdulrhmanalfawaz]

Probably the best vid this problem. Great job

[curtistrinh]

In case it is not clear, Solution(2), we use the theta= 30 and plug it into V_bR*costheta to find the vertical component/component crossing the river.

What sort of glass blackboard is this for someone like me from the Stone Ages?

This is a great tool and you do a great job of explaining these concepts so thank you! I have one question. It seems like the students are sitting directly across from where you are facing and you are writing on the invisible board in such a way that everything is properly oriented for the students/viewers. Are you writing everything backwards or is there something in this set up I don't understand?

[WarHawk]

I had more of a struggle telling whether you flipped the video horizontally after recording it than solving the problem. at 4:37 you hold up your right hand with a wedding ring on it...so I assume the video is flipped horizontally, but then you're calling on people in front of you to answer...so they can obviously see it too.

[jdeavraj]

Shook... how can you write backwards!!!
