هذا السؤال جائني في الاختبار و أرجو منكم الحل لأنني محتاج الأجابة ضرووووري

A motorist is driving a car of mass 1000 kg at 72 km/h. Find the kinetic energy of the car.
Then, a child runs onto the road 40 m in front of the car.
The motorist has a personal reaction time of 0.6 second. ( This means 0.6 seconds will pass before he is able to apply the brakes after he sees a hazard).
If the average braking force of the car is 8000 N, will the motorist be able to stop the car in time?
