Mass of the motor car = 1200 kg
As only two persons manage to push the car,hence, the acceleration acquired by the car is given by the third person alone.
Acceleration produced by the car, when it is pushed by the third person,
is a = 0.2 m/s2
Let the force applied by the third person be F.
From Newton’s second law of motion: Force = Mass × Acceleration
So,F = 1200 × 0.2 = 240 N
Thus, the third person applies a force of magnitude 240 N. Hence, each person applies a force of 240 N to push the motor car.
