A charged particle of mass m=1.116 g and charge q=0.968 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=7.02 kV/m. The particle started at position x0=z0=0 with the initial velocity v0=v0i, the initial speed being v0=0.74 m/s.

At some point later in time, the particle is found in a position with the z-coordinate z=-32.8 cm. What is the x-coordinate of this position?:
x= ____cm.

What is the speed v of the particle at this position?:
v= ____ m/s.
