coefficient of restitution

dimensionless (no units) number representing the ratio of separation velocity to approach velocity after impact of two bodies or objects. Dependent on elasticity of the objects. For example, during impact of a golf ball on a golf club face, ball and club deform and then rebound, which means that the ball increases its velocity. Likewise with a ball and racquet strings.

Table 2 shows the value of the final speed of the test vehicle and the restitution coefficient with respect to the mass of the previously selected vehicles.
By obtaining the restitution coefficient values, it is observed that decreased values exist when increasing vehicle mass, that is, the coefficient decreases for each of the vehicles from lower mass to greater mass.
The mechanism stopped the lighter vehicles at a greater distance, but due to the effect of the restitution coefficient they were travelling at higher speed; these small distances were not relevant, given that after being impacted in the rear the test vehicle never reached the impact barrier.
