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

Suppose you're riding your bicycle in the mountains. You climb a mountain pass on a scenic roadway and prepare to descend the other side of the mountains. You have a choice of two roads you can use to descend. One road is two miles long, while the other is ten miles long. Assuming you apply the same, consistent braking force throughout the duration of your descent for either route, which descent route will allow you to reach the base of the pass with the highest speed? Two-mile (shorter) route Ten-mile (longer) route No difference

Question 9– answer all parts A heavy goods vehicle of total mass 4.8 tonnes descends a hill with a gradient of 8 degrees from the horizontal. During this motion, the vehicle experiences a rolling resistance to its motion of 880 N. Whilst travelling at a velocity of 72 km/h, its brakes are applied, and the truck is brought uniformly to rest in a distance of 140 m. During this period of constant deceleration, it may be assumed that the rolling resistance remains constant at 88ON, this being in addition to the retarding force applied by the brakes. Calculate for the vehicle whilst it is slowing down: a) The vertical height through which it descends. b) Its decrease in potential energy. c) Its initial velocity in m/s. Its decrease in kinetic energy. -------------------- ---------------- -------------- ---------
