While traveling at constant speed, a 2100-kg vehicle encounters a banked, horizontal curve of diameter 0.50 km. (a) If the road grade of the bank is 6.0%, determine the angle between the road surface and the horizontal. (b) If the coefficient of friction between tires and the road is 0.80, determine the vehicle's maximum safe acceleration. (c) What is the net force on the vehicle in this case? (d) Suppose instead the driver, initially traveling at 15 m/s, wants to increase speed by 45% in a straight-line distance equal to the diameter above. Determine the required minimum power.
