From Newton's equation, F=m*a
Here, a is the acceleration. it can be written as, a=v/t
then substitute in above expression,
F=m*v/t
rearrange the term, v=F*t/m
Here m is the mass of the car, m=0.25 kg, F is the Force exerted on the car is ,F=40 N and t is the time,t=0.008 s
substitute the values in above expression, then
v=(40 N*0.008 s )/(0.25 kg)
= 1.28 m/s
this is the final speed of the car after collision, v=1.28 m/s
