A paleontologist scouts for potential dig sites (for dinosaur fossils) near the Red Deer River in Alberta (Canada).
She starts out at the coordinates x = + 400 m, y = + 200 m, as shown in the figure.
First she undergoes a displacement D, = – 700m î – 100mj, traveling a distance of 800 m in 3 hours.
Next she undergoes a displacement D, = 200 m i – 300 m ĵ , traveling a distance of 500 m in 2 hours.
Then she stops to rest, for 1 hour.
Finally, she undergoes a displacement D, with scalar components D3x
= + 500 m, D, = - 100 m
while moving through a distance of 1200 m in 4 hours.
