I can't really be bothered to explain,
but no. Speed is relative to time and space. The ball went from a standing start relative to its position, which was static at the time of ignition. It would therefore be doing 60 mph and would travel as such. The fact the platform is moving is immaterial.
Think of it if it fired forwards. Would the ball stay in the barrel despite all that chemical energy behind it? No. It would fire. And the same goes for backwards.
