A small particle with positive charge q=+4.25×10^−4 C and mass m=5.00×10^−5 kg is moving in a region of uniform electric and magnetic fields. The magnetic field is B=4.00 T in the +z-direction. The electric field is also in the +z-direction and has magnitude E=60.0 N/C. At time t = 0 the particle is on the y-axis at y=+1.00 m and has velocity v = 30.0 m/s in the +x-direction. Neglect gravity.

What are the x-, y-, and z-coordinates of the particle at t = 0.0200 s?

What is the speed of the particle at t = 0.0200 s?
