A 1500 kg automobile that has 2 m of frontal area is driven on a surface and the coefficient of rolling friction is 0.0015 for all speeds. Assuming minimum theoretical stopping distances, if the vehicle comes to a stop 76 m after brake application on a level surface and has braking efficiency of 0.75. what is its initial speed a) if aerodynamic resistance is considered and b) if aerodynamic resistance is ignored? Note: g-9.81 m/s? matin. The roadway is wet with good pavement. > The automobile is traveling at an elevation of 1500 m.
