    Are you assuming that the projectile is fired at such an angle that would be the same as the position of the plank before it started moving? This isn't particularly complicated to solve, just will require a few pieces

    start with the collision. We know that the impact must occur when the stone is moving at 45-degrees, so the x- and y-components of its vector velocity must be equal. The impact must also occur at a height of 3.0m from the ground, since the plank moves purely horizontally

    you'll end up with a system of equations to solve simultaneously, but I don't have it done yet
