varying acceleration

Question

Kizaru is a Navy admiral which is also a logia type devil fruit eater who possesses light beam powers. He can travel as fast as the speed of light. He was set to go to marineford wherein the “War of the Best” will happen which will include Fire Fist Ace, Edward “Whitebeard” Newgates, Navy Admirals, the 7 Shichibukai and the great Buggy the Clown. From the Navy HQ, he started at rest when t=0, therefore V=0 and during the course to marineford; his acceleration is best described by this equation

Answer 1

Basic dynamic equation

v = u +at

Here v is the final velocity , u is the initial velocity , a is acceleration , and t is the time.

At t =0 ; u =0

v = 0 +at

a = v/t
