M201 X1500.00 Y1500.00 Z120.00 E5000.00 ; set accelerations (mm/s^2)
Speed acceleration and jerk are defined in your config.g here.
You can also specify M204 P T which is acceleration for print and travel moves, so you can have faster travel moves.
M205 etc are the marlin gcode commands for those things. they are also supported in reprap, so it's really up o you what you want to use.
