QUESTION 5 A bus accelerates from rest to 0,067 \( 0.04 \mathrm{~km} / \mathrm{h} \) in 17 seconds; it continues with this speed for rest. Plot a velocity time graph for the journey then calculate. 5.1 The total distance covered. 5.2 The average speed for the whole journey

Quick Answer
The total distance covered by the bus includes the distance during acceleration and the distance during constant speed. The distance during acceleration is approximately 0.157 meters. The distance during constant speed depends on the duration \( t_c \) the bus travels at this speed. The average speed for the whole journey is calculated as the total distance divided by the total time, which includes the 17 seconds of acceleration and the additional time \( t_c \) at constant speed.
