Alright it looks like "PHY_OnObjectCollideWithSAWorld" same for "ColideWithPlayer" doesn't work properly..
I even used them on the ball example you provided

pawn Код:

public PHY_OnObjectCollideWithSAWorld(objectid, Float:cx, Float:cy, Float:cz) {
    if(objectid == dropid || objectid == drop2) {
        SendClientMessageToAll(-1, "Reached the ground");
        PHY_DeleteObject(dropid);
    }
    return true;
}
public PHY_OnObjectCollideWithPlayer(objectid, playerid) {
    if(objectid == dropid || objectid == drop2) {
        SendClientMessageToAll(-1, "Reached the ground");
        PHY_DeleteObject(dropid);
    }
    return true;
}

pawn Код:

new drop2;
CMD:ball(playerid, params[])
{
    new Float:x, Float:y, Float:z, Float:ang, Float:vz, Float:mass;
    sscanf(params, "F(0.0)F(1.0)", vz, mass);
    GetPlayerPos(playerid, x, y, z);
    GetPlayerFacingAngle(playerid, ang);
    new a = CreateObject(1598, x, y, z-0.69, 0, 0, 0);
    drop2 = a;
    PHY_InitObject(a, 1598, mass, _, PHY_MODE_3D);
    PHY_SetObjectVelocity(a, 6.0 * floatsin(-ang, degrees), 6.0 * floatcos(-ang, degrees), vz);
    PHY_RollObject(a);
    PHY_SetObjectFriction(a, 0.25);
    PHY_SetObjectAirResistance(a, 0.1);
    PHY_SetObjectGravity(a, 7.1);
    PHY_SetObjectZBound(a, _, _, 0.5);
    PHY_UseColAndreas(a);
    PHY_ToggleObjectPlayerColls(playerid);
    return 1;
}
