The brakes exert a 1,951 n force on a car weighing 18,985 n and moving at 12 m/s. the car finally stops. how long (in seconds) does the braking force act on the car to bring it to a halt?

volume: 22

density: 7.04

not too sure thinking all accelerations are pointed down

3. dark matter

empty space could also be a simple vacuum
