PROBLEM 1: A car travels a 10-degree inclined road at a speed of 20 ft/s. The driver then applies the break and tires skid marks were made on the pavement at a distance "s". If the coefficient of kinetic friction between the wheels of the 3500-pound car and the road is 0.5, determine the skid mark distance. PROBLEM 2: On an outdoor skate board park, a 40-kg skateboarder slides down the smooth curve skating ramp. If he starts from rest at A, determine his speed when he reaches B and the normal reaction the ramp exerts the skateboarder at this position. Radius of Curvature of the
