A sort of "projectile launcher" is shown below. A large current moves in a closed loop composed of fixed rails, a power supply,

and a very light, almost frictionless bar touching the rails. A magnetic field is perpendicular to the plane of the circuit. The bar has a length of 20 cm, a mass of 1.2 g, and is placed in a field of 1.7 T.
a) What constant current flow is needed in order for it to accelerate to 33 m/s in a distance of 1.0 m?

b) In what direction must the field point?

PLEASE ANSWER OR ATLEAST TRY!!! Please and thank you.
