Would I use v^2 =v_o^2 +2ad? and solve for d? but would I also use F=ma to find a?

The fragment whose speed is zero, must have had momenum applied to it in the horizontal direction to "stop". That momenum is - 1/2 m vhorizontal, as it was going vhorizonal at the time. That means the other piece has 1/2 m vhorizontal applied to it, and it moves with m vhorizontal forward.

So, since it's mass is 1/2 m, it now has twice the horizontal speed (2*20cos60).

Figure the time it takes to get to the top. Then it takes the same time tofall, but the bulliet piecce is going twice as fast.
