What equation should be used then to isolate t?

Since v=(-x/100)*(mg/b), I used kinematics equation d=vit+1/2 at^2, assuming a=0, I found t to be -100d*b/mgx

But how would I lead it all back to proving this Δy= (v^2ty/g)*[(X/100)-ln((100-x)/100))

Homework Statement Assuming that the drag force magnitude is given by the equation D= bv, where b is the drag parameter and v is the instantaneous velocity magnitude of the object. (a) Show that the vertical displacement through which a dropped object must fall from to reach X% of its...
