You should do a video on the arc length of a function and the way the formula is derived. Thanks again I love your videos

[@physicsloverjoinmychannel2937]

i do not understand

[@sakariyecabdirisaaq2114]

thanks

[@KrishnaKumar-zx5lp]

please send like of flag problem kinematics

At very end, I don't understand why avg acceleration will be in units of (m/s^2)? If integral of acceleration on right hand side is correct than that should be velocity or in units of (m/s). And (1/B-A) is in units of (1/m) so when you multiply (1/m) by (m/s) you end up with (1/s) not (m/s^2). What am I doing wrong?

[@KhanAcademyPoPolsku]

B-A is a time interval, sp 1/(B-A) is im seconds, not meters

[@Taransidhu21]

How do we calculate if it is between 3 time intervals instead of just 2 as shown in the video??

[@krystalthomas7282]

the anti derative of 12t^-4 = -4t^-3 + C and C = 1 still gives 3.5 as the answer. Yikes!

You have to translate this video to Arabic
Because Arabic people loves your video .
