I will mark you as brainliest. if you answer my question

First, let's list everything we have...

a = 1.83 m/s^2

F = 1870 N (converted from kN to N)

vi = 0 m/s (it says started from rest, therefore velocity starts at 0)

t = 16 s

1). "Force acting on the car" is a bit ambiguous because there are many forces. But I'm going to assume that they are looking for just a basic implementation of force equation:

where:

F = force

m = mass

a = acceleration

2). I recommend memorizing your equations of motion, because once you know them this part is also just as easy:

where:

vf = final velocity

vi = initial velocity

a = acceleration

t = time

car stops. he keeps going = he has inertia
