  • $\begingroup$ I think your former self is wrong. You basically computed the final speed of the block if it had been released at the top of the ramp and had slid down a distance $d$ against friction. $\endgroup$

    $\begingroup$ Setup seems correct. For reasons which may be aesthetic, I would have put the $W$ term on the right side of the equation, reflecting that that amount of work has been disippated by friction in final state $f$. But it's mathematically the same $\endgroup$
