kotykmax [81]

Answer:

The acceleration of the car is 5m/s²

Explanation:

Given data

Force F= 4,000N

Mass of car m= 800kg

Acceleration a= ?

Applying the Newton's second law of motion which states that the rate of change of momentum of a body is proportional to the external force and takes place in the direction of the force

F=ma

a= F/m

a= 4000/800

a=5m/s²
