Like getting suddenly smashed in your seat: Tried but couldn't do it.

NO !! Do your own homework, or you will never learn.

It depends on the time it took to accelerate. Say the car accelerates from 10 m/s to 44 m/s in time t [in seconds]. So the change in velocity is 34 m/s, and the acceleration (over that time period t) is 34 m/s / t. Force is defined by Newton's Second Law of Motion as the change in momentum. If the mass of the car is constant at 600 kg, then we could say that the force equals mass times acceleration (over that time period t). F = m a = 600 kg 34 m /s / t. F = 20400 / t[s] N

No idea.
