An aircraft of total mass 1.5 x 10^5kg accelerates at maximum thrust, from rest along a runway for 25s reaching the required take off speed of 65 ms^-1.

Assume that the acceleration of the aircraft is constant. Calculate the distance travelled in this time.

My attempt:

I know s = ((u+v)/2) x t

So I did 65/2 x 25 = 812.5m but u feel like this is too simple and acceleration should be involved here because it's given me the mass of the aircraft?

Any advice?

Many thanks!
