You are designing a system meant to stop runaway trucks that lose control on highways, and your design consists of a flat section leading up to a sandy pit like the one shown in the photograph. In your design, you also include a spring barrier at the top with an effective stiffness of k = 2 kN/m that can compress 10 m from its natural position. A. What is the maximum speed that a runaway truck of 2 metric tons can have if it comes to restvwhen the spring barrier experiences maximum deflection? B. Will the truck slide all the way back down the ramp or will it stop midway? Prove your answer. Box TRUCK SMOOTH //// RUNAWAY TRUCK RAMP 150m -1 k Lumi ROUGH, 1, =0.5
