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 of 12 m s⁻¹, it is not accelerating. According to Newton's first law of motion, when an object moves at a constant speed, the resultant force acting on it is zero. This means that the forces acting on the vehicle are balanced, and there is no net force causing acceleration.
