hmm, weird. i still see it. the first 5 chapters on the website include all new lectures,  you can just watch them there for now.

Thanks AK, Good stuff.

I have a similar problem to this where a slider is pulled along in a slot (ignoring friction) by a cable that is attached to an offset point. So as the slider moves, the component of force along the slot changes (reduced in this case), Using cos(theta) derived into an equation involving only the distance x of the slider from its final position i have been able to write a function for the force that i can integrate over that distance.
The initial distance is 1.2m from the end, and the final dist is 0m. However when i integrate i get a negative number.
Im fairly sure i can just flip the sign and use this still, but could you or someone explain what i need to consider here and why

Great video! Also, I think your shirt is inside-out lol.
