To avoid using the variable "a" which of the following equations should you use?

a) v² (f) = v² (i) + 2aΔx
b) v (f) = v (i) +at
c) Δx = 1 / 2 ( v (f) + v (i) ) t
d) Δx = v (f) t - 1 / 2 at²

hi im pretty sure these are called 1D kinematic equations! thanks!

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?
