The new flexible polymer and carbon composite boom is coupled with a twelve-unit (12U) CubeSat built by NanoAvionics. After the mission launches atop a Rocket Lab Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand, the spacecraft will go into a Sun-synchronous orbit at an altitude of about 600 miles (~1,000 km) and the sail will deploy in about 25 minutes to cover an area of 860 ft² (80 m²) with the boom unfolding from the size of a hand to 23 ft (7 m) long. Once deployed, the sail will adjust the vehicle’s orbit by angling itself in relation to the solar wind.
While railguns are known for rapidly accelerating projectiles to hypersonic speeds over the short length of a gun barrel, there's no limit on how slowly they can accelerate something or how long the "rail" part of the railgun can be. Accelerating "slowly" over a long distance is totally possible!
That would put the g-forces back in play: the faster you go around the rail the stronger the centripetal force that keeps you going in a circle. If the rail is straight the force only depends on acceleration not speed.
