Answer:
it can use F=ma equation.F=force,m=mass of the object,a=acceleration of the object(to the move direction.)
Explanation:
force does 3 persons push the motorcar=mass of car * acceleration of car
=600 kg * 0.2 m/s square
=120 kgm/s square
(kgm/s square = N)
so, = 120 N
force does each person push the motorcar = 120 N / 3
= 40 N
