10. The coefficient of kinetic friction between a rubber tire and a wet concrete road is 0.5. (a) Find the minimum time in which a car whose initial velocity is 50 km/h can come to a stop on such a road. (b) What distance will the car cover in this time?

The simply supported beam consists of a w410 × 60 structural steel wide-flange shape [e = 200 gpa; i = 216 × 106 mm4]. for the loading shown, determine the beam deflection at point c. assume p = 69 kn, w = 79 kn/m, lab = lbc = 1.3 m, lde = lcd=1.6 m, ma = 168 kn-m.
