Jilla VS BillaClassical Mechanics Level pending
The Jilla- a supercop who never lost a single criminal he handled. The Billa- the most wanted thief in the whole world. Who might win? When the weapons industry drew blueprints for a highly unstoppable weapon, the Billa stole it. When all the cops feared the Billa, it was up to Jilla to stop him. Jilla found his base and was coming to Billa's room to capture him. Bill, however didn't want the blueprints to ever exist. Billa had a safe and wanted to blow it up (The safe had the blueprints). He had 4 kinds of bombs- circle, cone, sphere and square. He blew the safe but the blast did not harm the blueprints and, Jilla put him in jail and saved the blueprints.
Which kind of bomb should've Billa used?
