_________here is ur answer______
according to newton's second law of motion
F=ma
Given data:
mass=0.2kg
velocity=20m/s
time =0.4sec
now :-
F=ma ------1
we know that acceleration is the rate of change of velocity I.e :- a=v/t put this in equation 1
F=mv/t
F=0.2×20/0.4
F=2×20/4
F=40/4
F=10N
so answer is 10N
