Question

A charged particle of mass m=1.14 g and charge q=1.03 μC is moving in the xz-plane (unit vectors i and k) under the action of both Earth's gravity g=−g k and the electric field E=−E i, where magnitude E=15.9 kV/m. The particle started at position x₀=z₀=0 with the initial velocity v₀=v₀i, the initial speed being v₀=0.5 m/s.  

At some point later in time, the particle is found in a position with the z-coordinate z=-33.8 cm.

What is the x-coordinate of this position?:

What is the speed v of the particle at this position?:
