A particle (q = 4.0 mC, m = 50 g) has a velocity of 25 m/s in the positive x direction when it first enters a region where the electric field is uniform (60 N/C in the positive y direction). What is the speed of the particle 5.0 s after it enters this region?
 a. 49 m/s
  b. 35 m/s
  c. 32 m/s
  d. 44 m/s
  e. 24 m/s

Question 2

A particle (q = 3.0 mC, m = 20 g) has a speed of 20 m/s when it enters a region where the electric field has a constant magnitude of 80 N/C and a direction which is the same as the velocity of the particle. What is the speed of the particle 3.0 s after it enters this region?
 a. 68 m/s
  b. 44 m/s
  c. 56 m/s
  d. 80 m/s
