Why is a truck harder to stop than a car?

The higher the mass of an object, the more momentum it has, and the harder it is to stop or turn. Fully loaded, a semi-trailer truck has a mass 20 to 50 times that of a four-wheeled automobile. This fact means that it is 20 to 50 times harder to stop or turn a truck than a car simply because of its momentum.
