Worked Solution & Example Answer:A vehicle is driven at a constant speed of 12 m s⁻¹ along a straight horizontal road - AQA - A-Level Maths Mechanics - Question 10 - 2020 - Paper 2
Step 1
The resultant force acting on the vehicle is zero.
Answer
Since the vehicle is moving at a constant speed, it is not accelerating. This implies that the forces acting on the vehicle are balanced. The driving force and the resistive forces (friction, drag) are equal, resulting in a net force of zero. Therefore, the correct statement is that the resultant force acting on the vehicle is zero.
