Answer:
a) Since the woman starts from rest hence her initial velocity equals 0 m/s.
b) We can calculate the final velocity as follows
1) Distance covered while accelerating for 9 seconds is
2) Cruising speed =
Distance covered while travelling for 15 minutes at cruising speed =
Since the woman cover's 27 km in total hence the speed she travles with traffic speed can be calculated as
hence the final speed of woman =
Average velocity =
Her velocity 9 seconds into trip is calculated earlier as 22.5 m/s
