The distance needs to be further apart from the car in front
As trucks are generally heavier than cars they require a longer distance to stop.
Most cars can stop from 60 mph in about 100 feet or so. If the relationship is linear then a car should stop from 30 mph in about 50 feet.

depends on how heavy the cars is. depend on the brakes and the tire performance
The force of gravity will also depend on the distance between the cars. Choose a suitable distance, then replace the numbers in the formula for gravitational attraction.
That depends upon the braking ability of the car, the condition of the tyres and road surface. Also the alertness of the driver will have some effect. If you are referring to the emergency stopping distance as suggested by the UK Government in The Highway Code publication (which has not been updated for modern cars) for a dry road and a car with good brakes and tyres, then the stopping distance is 20ft for the thinking distance plus an actual stopping distance of 20ft making a total of 40ft. The table of stopping distances is given by: d = speed + speed2 ÷ 20 where the distance d is in feet and speed is in mph. At 70mph this equates to 315 feet ~= 96m which is almost 100 metres - the distance between marker posts along the side of a motorway!
Six car lengths is a good distance.
When you will observe the road far ahead of the front end of your car and keep proper distance between other cars, then you will have enough time for thinking and enough space for braking. But when intense situation happens, then the thinking and braking are solidified in one desperate move: to avoid a collision.
you should give at least a foot of space...
