Question

An 855 kg dragster accelerates from rest to 120 km/h in 0.90 seconds.

What is the average force exerted on the car?

I used the regular f=ma which is f=855*(120-0/.9) which equalled 114000 but that answer is wrong. I don't know another formula am i supposed to add in the gravity force and things like that??
