heyy..here is ur ans..
u = 15m/s
v = 0
t = 5s
acceleration = v-u/t
= 0 - 15 / 5
= -3 m/s^2
so d negative acceleration is 3m/s^2
hope it helps u...if it did plzz mark me brainliest....thanks....!!!

JINGO:
It will be only 3 as it is already said in the question as NEGATIVE ACCELERATION MEANS RETARDATION.
see my solution. U are correct but it is given negative acceleration.

initial velocity (u)=15 m/s
final velocity(v)=0m/s
time(t)=5 secs
v=u-at(negative acceleration)
0=15-5a
5a=15
a=3
Therefore negative acceleration is 3m/s^2
