Two cars of the same make, one with a load and the other without a load (empty), move at the same speed.

Two cars of the same make, one with a load and the other without a load (empty), move at the same speed. If each of them collides with an obstacle (for example, a concrete post), which car will be more damaged? Why?

The kinetic energy of a body is determined by the formula: E = m * v ^ 2/2, where m is the mass, v is the speed. In a collision, it completely passes into the internal one, that is, it goes to destruction and to heat the body. Obviously, the car with the cargo will be damaged more.
