2.) A test car furnished with antilock braking system stops at 88 m distance when brakes are applied at 100 km/h speed while travelling down a 3% grade on a test track with poor, wet pavement. During one of the tests at the same speed, the test car impacted an object at 100 m distance from the point of brake application on the same test track. The investigators found out that the antilock brake system failed 60 m after the brakes had been applied. What speed was the car travelling at just before it impacted the object? Notes: i. Assume theoretical braking distance ii. coefficient of road adhesion (maximum) = 0.60, iii. coefficient of road adhesion (sliding) = 0.30, coefficient of rolling resistance = 0.015, iv. V. mass factor = 1.04

Q8. The sports car is traveling along a 30° banked road having a radius of curvature of p = 400 ft. If the coefficient of static friction between the tires and the road is µç = 0.19, determine the maximum safe speed so no slipping occurs. Neglect the size of the car. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. Take g 32.2 ft/s². = Your Answer: Answer units 0 = 30°
