A small object, which has a charge q = 7.5 C and mass m = 9.0

Question:

A small object, which has a charge q = 7.5 µC and mass m = 9.0 × 10-5 kg, is placed in a constant electric field. Starting from rest, the object accelerates to a speed of 2.0 × 103 m/s in a time of 0.96 s. Determine the magnitude of the electric field.
