I found your videos a couple days ago and I'm so glad that I did!! It seems you teach from the same book as my instructor, except that I can't understand my instructor! Thank you for making these. Subscribed!!

Man you are so awesome!

God damn i was looking for a problem like this for SOOOOOO long Thanks for explaining!

[@shivpalpatine]

at 13:20 why dont you integrate the same way as 6:40 with the +C??? At 13:20 you integrate with bounds (0 to U and also 0 to T) but at 6:40 you integrate and just add the +C??? Couldnt you use the initial condition at t=0 the acceleration = 0 and velocity = 0?

[@michellerahmoeller191]

I'm not sure if you're interested in the answer anymore but for anyone watching this video and wondering the answer to this.... You could have integrated with bounds at 6:40 rather than doing a boundless integration with +C. It will give you the same answer. You would integrate dm(cv) from 400 to m(cv) on the left and integrated -m(e)dt from time 0 to time t and you will get the same expression. If in doubt, grab a pencil and try it out! Hope this is helpful to someone!!
