let me rephrase that just for you , so that you can comprehend it.

Quote:
so the 100 kg mass passing through the turn that is experiencing a speed increase from 40 m/s to 67 m/s
in 1 second experiences an acceleration of 27 m/s/s


therefore

a = (sf - si)/t

where
a = acceleration m/s/s
s = speed
t = time in seconds
f = final
i = initial

a = 67 m/s - 40 m/s / 1 second = 27 m/s/s
