A particle (m = 20 mg, q = 5.0 C) moves in a uniform electric field of 60 N/C in the positive x direction. At t = 0, the particle is moving 30 m/s in the positive x direction and is passing through the origin. Determine the maximum distance beyond x = 0 the particle travels in the positive x direction.
 a. 25 m
  b. 20 m
  c. 15 m
  d. 30 m
  e. 60 m
