A car travels along a straight, level road.
The horizontal forces on the car are a driving force of 2400 N forwards and a total resistive force of 1800 N backwards.
The mass of the car is 1200 kg.
Calculate the resultant force on the car.
Give the direction of the resultant force.
State the equation linking force, mass and acceleration.
Calculate the acceleration of the car.
Later in the journey, the resistive force increases until it is equal to the driving force.
Describe the motion of the car now.
