80 kg.m/s/s * 50 s = 4000 kg.m/s/s ??


the same as saying

80N * 50 seconds = 4000N

1 N = 1 kg·m/s2

you do realize that time is part of a newton dont you?

1 newton unit of force = 1kg per meter per second per second

so

2 newton units of force = 2 kg meters per second^2

or

2 newton units of force = 1 kg meters per 2 seconds^2

so

4000N = 80 kg meters per 50 seconds^2

which is

4000N = 80N * 50 seconds
or
80N * 50 seconds = 4000N
