Sorry bro but I think the distance between the points is required because the answer depends on it.
HINT
Take B on the origin and A at (-d,0) and C at (d,0) now position of A after time t is (-d,vt) and that of C is (d,at2/2) now from these points write eqn of line in two point form and put x = 0 to obtain a relation between y co ordinate of B and the rest of parameters.
- Simplify the eqn and compare to the standard eqn for distance s = ut + at2 /2 to obtain the initial velocity and accn.
NOTE : The solution is in general for the point except the bullet because in that point the acceleration has been assumed to be constant otherwise problem becomes too complex.
