I will set up the solution for you, but YOU do the calculations.
a = constant ⇒
v(t) = v0 + at ⇒
t = [v(t) - v0]/a
Get a from kinematics.
v2 - v02 = 2ad ⇒
a = (v2 - v02)/(2d)
Plug in
v = 4.18 x 106 m/s
v0 = 17,800 m/s
d = 0.0102 m
and get a in m/s2. Then plug a, v, and v0 into
t = (v - v0)/a
and get t in seconds. You should be able to finish from here.
