The net force acting on the automobile is 3600N
The acceleration of an object is directly proportional to the net force acting on it.
The acceleration of an object also depends upon its mass.
Acceleration (a) = net force (F) / mass (m)
a = F / m
Given that; a = 3 m/s², m = 1200 kg, hence:
3 = F / 1200
F = 3600N
The net force acting on the automobile is 3600N
