One Member of a Pair of Parallel Conducting Plates Has $\times$

One member of a pair of parallel conducting plates has potential 17 V. An electron is ejected from that plate at potential and travels the other plate,attaining a velocity of 5.0 $\times$ 10⁶ m/s when it arrives.What is the potential of the second plate? The mass of the electron is 9.11 $\times$ 10^-31 kg.

A) 157 V
B) 89 V
C) 72 V
D) -54 V
E) 142 V
