Explanation / Answer

v = 5*10^6 m/s
E = 10^3 N/C
a) F = qE = 1.6*10^-16 = m*a
a = 0.1758*10^15 m/s/s
2*a*s = v^2
s = 0.07109375 m
b) v = at
t = 2.844141069397042093287827076223e-18 s
c) s = 8 - 7.109375 = 0.890625 cm
2*a*s = v^2
v = 17695868.161805455765690456225634 m/s
KE = 0.5mv^2 = 0.00000000000000014248040625 J
KE old = 0.5*m*(5*10^6)^2 = 0.000000000000000011375 J
Fraction lost = 11.52
