Same question. Different marks.
ChatGPT gets the answer right but scores zero. ExamPal shows the working that earns every mark.
A car of mass 1200 kg accelerates from rest to 15 m/s in 10 seconds. Calculate the resultant force acting on the car.
[2]The resultant force acting on the car is 1800 N. This is because when a car accelerates, the net force can be calculated using Newton's second law of motion, which states that force equals mass times acceleration. Since the car goes from 0 to 15 m/s in 10 seconds, the acceleration is 1.5 m/s², and multiplying by the mass gives us 1800 Newtons.
Correct answer, but no working shown. CIE awards 0 marks without substitution steps.

Examiner tip: Always show substitution separately. Writing just "F = 1800 N" without working loses the first mark.
