The "src" in the package name means source code, so you have to compile the package before you can use it. You generally would use this type of package if you wanted to customise the software. There are lots of sites that will tell you how to compile software.
But even easier, go back to wherever you got the rpm from and download one with the same name, but without "src". Use the same command to install it.
After that, how you run the software depends on the package - look for some documentation where you got the rpm, or try "rpm -qlp <package> | grep -i readme". Often a good place to start is with the binaries; "rpm -qlp <package> | grep bin" will list those for you.
