The pickup truck weights 4890 lb and reaches a speed of 58 miles/hr from rest in a distance of 300 ft up the 15-percent incline with constant acceleration. The effective coefficient of friction between the tires and the road is known to be at least 0.60. (a) [40 pts] Calculate the normal force under each pair of wheels and the friction force under the rear driving wheels. [hint: front wheels are free to rotate, that is friction is negligible under the front wheels); 1 mile = 5280 ft] (b) [5 pts ] How do you know if your answers are correct? State your reasoning or present an alternative method to solve the problem. (Hint: this may include ways such as unit checking, intuition, alternative methods, group discussion etc.) 1.5ft А B 11 -4.5ft 4.5 ft 15
