An electron moves at 35times106 ms into a uniform

Question

An electron moves at 3.5×10⁶ m/s into a uniform electric field of magnitude 429 N/C. The field is parallel to the electron’s velocity and acts to decelerate the electron. How far does the electron travel before it is brought to rest? The fundamental charge is 1.602×10¹⁹ C and the mass of an electron is 9.10⁹×10³¹ kg . Answer in units of cm
