I used exactly the same reason you used to say

40N * 10s = 400N
which of course is the same as
40 kg.m/s/s * 10s = 400kg.m/s/s


even your above shows that

80N * 50 seconds = 4000N is correct

because

40 kg.m/s/s = 40N
400kg.m/s/s = 400N

just like

80 kg.m/s/s = 80N

and therefore

80N * 50 seconds = 4000N is correct
