Answer question 8

2. The driver of a car travelling at a certain speed suddenly sees an obstruction ahead and travelled a distance of 58.3 m during the perception-reaction time of 1.3 seconds. Determine the car's speed of approaching in kph. (1 pts)

I need the answer as soon as possible

4. C per The maximum flow rate on a road is 1000 vehicles hour and the free flow speed is 80 km/h. For an instant when the traffic is flowing at 70% of the maximum flow rate, determine; Ci) the two possible speeds? the two possible spacing the two possible headways? (i) Cili)

Problem Statement Consider isentropic supersonic flow around the sharp expansion corner illustrated in Figure shown below: Mi M2 Figure 1. Isentropic supersonic flow around a sharp expansion corner. The relationship between Mach number before the corner (M₁) and after the corner (M₁), derived by Zucrow and Hoffman (1976), is given by o = bâ [tan-t ཊཌི་ཊྛཱི -1」 བཻ _ tan-iཊཌི་ཤྲཱི -1 j -[tan-t{wę - 1)2} - tan-i{of - 1)4}] where b b = (x + 1) and y is the specific heat ratio of the gas. Use Newton-Raphson Method to solve for M₂ for specified values of y, 6, and M₁. For y = 1.4, solve for M₂ given the following combination of M₁ and 6: 1.0 and 10.0°. Correct up to 1.0x105.

As a car comes around a bend onto a straight road moving at 80 km/hr the driver suddenly notices another slower car ahead, a distance d = 50 m ahead, moving at 30 km/hr. At this moment, in order to avoid hitting the slow-moving car ahead the driver slows down but takes .25 seconds to react relative to first noticing the car 50 m ahead. Assuming the car decelerates at a constant rate, above what minimum magnitude of the deceleration avoids a rear-end collision? can you solve this with a detailed explanation

crossing the road from far ahead, after many attempts to reduce the speed but he A car was traveling at 130 kno ner hoILE and suddenly the driver seen someone Crossing the road from far abead after many attempts to reduce the speed but he colan't avoid hitting the man at distance of 165 meters, what was the estimated speed at hitting?
