A long, straight wire lies along the x-axis and carries current I = 50.0 A in the +x-direction. A small particle with mass 3.50 × 10⁻⁶ kg and charge 8.00 × 10⁻³ C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 8.00 cm, its acceleration has components aₓ = -5.00 × 10¹ m/s² and aᵧ = +9.00 × 10¹ m/s². At that instant, what are the x- and y-components of the velocity of the particle?
