I didn't have much trouble with the 1-D 1 object kinematics, but I'm having a lot of trouble with 2 objects. I'd just like some help setting the problem up:
Two stones are dropped from the edge of a 60m cliff, the second stone 1.6s after the first. How far below the top of the cliff is the second stone when the separation between the two stones is 36m?
I thought the best way to set this up would be:
X = Displacement of first stone in terms of a
Y = Displacement of second stone in terms of a
X-Y=36m
(vt+.5at2)-(vt+.5at2)=36
(Pretend I have subscripts to indicate they aren't the same variables and don't cancel each other out right away.)
I don't know if that's right, and even if it is, I just can't think of how to factor in the 1.6s.
A little guidance on how to get started would be appreciated.
