v=at 27m/s=a(7s) a= 27/7= 3.86m/s^2 F=ma F= (1000kg)(3.86m/s^2) = 3860 N
FYI I am a physics student rn in college first semester of it. Bear with me if im wrong
a 1000 kg car is traveling 27 m/s over 7 seconds what is it average forward force of the car?
27 m/s x 7 s =189 m/s^2 = a
1000 kg x 189 m/s^2 = 189,000 N

That question makes no sense as asked.
Ideally it take ZERO force to maintain a constant speed.
FORCE implies ACCELERATION
F = m A
Now perhaps you mean it accelerated from zero to 27m/s in 7 seconds
a = change in velocity / change in time
= 27/7 =3.86 m/s^2
F = 1000 kg * 3.857 = 3,857 Newtons
