Constant Current Power Supply What Constant Current Flow Is Needed In Order For A Bar To Accelerate To 26 M/s In A Distance Of 1 M, Provided

What constant current flow is needed in order for a bar to accelerate to 26 m/s in a distance of 1 m, provided - constant current power supply

This whole issue:
Many movements in a closed stream of fixed rails, a power source and a very bright bar, touching nearly frictionless rails. A magnetic field perpendicular to the line. The bar has a length of 20 cm, a mass of 1.3 g were placed in a field of 1.7 T.
What constant current is needed to accelerate to 26 m / s over a distance of 1.0 m?

Any help is welcome.
