Solution :-
deceleration = ( final velocity- intial velocity)/ time
d= ( vf-vi)/t
d= deceleration
vf = final velocity
vi = intial velocity
t = time
So deceleration is
-114 m/s x 9.4 s or -1071.6 m/s^2
now
firce = mass × acceleration
so you get force = 720 kg x 1071.6 m/s^2 or 77155 Kg m/s^2
Unit of force being
kg m/s^2
