Question

Abody moves along astraight line from A-B wiz uniform acceleration 2/3ms velocity at B is 25m/s.find velocity at A.find distance A-B.

Answer 1

I need the answer from u.thanx

Answer 2

The somewhat vague requirements give rise to the following equations of motion:

a = 2/3
v + (2/3)t = 25
vt + (1/3)t^2 = B-A
or
25t - 1/3 t^2 = B-A

Without knowing how long it took to get from A to B (only knowing that it is less than 75/2 seconds - why?), that's all we can do.
