    I can help, if SNIIX18 isn't able yet. The car is accelerated because there is a force on it. This causes it to gain \(20m/s\) in \(5s\). Can you tell me the acceleration, then?

    And the "nope" was to your "just this once." I'm going to be stubborn, now, and not help you eliminate answers randomly. You'll have to get an answer from somebody else. I'll only guide you to it.

    Found it for sure? Found acceleration, and multiplied that by mass to see what the force must be?
