we investigate the motion of a charge in a uniform electric field. The
electric field is 200 N/C and is in the positive x-direction. The
particle has charge 10m C, mass 10 g and is
at the origin, moving along the y-axis at 10m/s at time t=0.
When does the particle reach x = 1 m? What is its y coordinate
The particle's acceleration is in the x-direction, with
This acceleration is constant, so the particle's motion in the x-direction
is described by equation 2.11 with vi = 0.
