**jai**, Friday, October 29, 2010 at 12:04amacceleration is change in velocity over time, or:

a = (v - v0)/t

where v = final velocity in m/s

v0 = initial velocity in m/s

t = time in s

assuming that it is initially at rest, v0 = 0,, the final velocity, v, is the speed of light, which is approximately 3.0 x 10^8 m/s

substituting:

2500 = (3.0x10^8 - 0)/t

now, solve for t.

hope this helps.
