A car (SUV) is to overtake a bus as it enters an acceleration lane. The speed of the SUV is 80 kph initially. The bus is at the same speed as the SUV. Given the perception reaction time as 2.70 seconds and the average acceleration of the vehicle is 2.55 m/s2, solve the following: a. The distance (in ft) traversed during the perception and reaction time and during the initial acceleration to the point of encroachment on the left lane. b. The distance (in yard) travelled by the passing vehicle occupies the left lane if the opposing vehicle travelled at 75 kph and the time for the passing vehicle to occupy the left lane is 20 seconds. c. The minimum passing sight distance (in m) if the SUV's velocity to overtake the bus is 55.92 miles per hour while the distance between the opposing vehicle and the SUV after its maneuver is 295 ft. The time for the SUV to occupy the left lane is 0.23 minutes.
