1.A race car has a mass of 707 kg. It starts from rest and travels 42.0 m in 3.0 s. The car is uniformly accelerated during the entire time. What net force is exerted on it?
Do I use F=ma so then m=707 and a=42/3 which is 14. So m=707 and a=14 and I multiply and it's 9898 N?

No the answer is 707/3.
