Question
a cyclist travels 2.5km east, then 10km south and finally 5km west. determine the cyclist's overall displacement from their starting point.
Answers
Damon
west = 2.5 km
south = 10 km
magnitude = sqrt(6.25 +100)
tan of angle south of west = 10/2.5 = 4
angle south of west = 76 degrees south of west
south = 10 km
magnitude = sqrt(6.25 +100)
tan of angle south of west = 10/2.5 = 4
angle south of west = 76 degrees south of west
