Last time now, with d $=2\mathrm{.}89$ m$.$ You start the block on the track at rest, somewhere to the left of x $=0.$ You then release the block from rest and let it slide down. What is the maximum value of x $($that is$,$ what is the closest to the origin$)$ from which you can release the block from rest and have it leave the track at x $=0$ and go into freefall? 

a$.-0\mathrm{.}74$ m

b$.-0\mathrm{.}71$ m

c$.-1\mathrm{.}45$ m

d$.-1\mathrm{.}03$ m
