A car of mass 500kg is travelling along a flat road. The forward force provided between the car types and the road is 300N and the air resistance is 200N calculated the acceleration of the car

Answer 1

300- 200 = m a = 500 a
so
a = 100/500 = 0.2 m/s^2

Answer 2

I don't know

Answer 3

300-200
a= F/m
100N/500kg
= 1/5
= 0.2m/s^2
