The total kinetic energy before the collision is not equal to the total kinetic energy after the collision. A portion of the kinetic energy is converted to other forms of energy such as sound energy and thermal energy. A collision in which total system kinetic energy is not conserved is known as an inelastic collision.
To solve this problem we will use the Force equation according to the definition given in Newton's second law. There we have that the Force is equal to
Where,
m = mass
a = acceleration
Our values are given as
Considering that both mass are equal to one, we have that:
Therefore the truck exert a force on the car of 11kN
