Rockfalls can cause major damage to roads and infrastructure. to design mitigation bridges and barriers, engineers use the coefficient of restitution to model the behavior of the rocks. the rock a falls a distance of 26 m before striking an incline with slope α = 40°. knowing that the coefficient of restitution between a and the incline is 0.2, determine the velocity of the rock after the impact.
