a woman walks 250 m in the direction 30 degree east of north,then 175 m directly east.A) using graphical methods,find her final displacement from the starting point.B) compare the magnitude of her displacement with the distance she walked.,
north displacement = 250 cos 30 = 216.5
east displacement = 250 sin 30 + 175 = 300
displacement = sqrt (north^2+east^2)
= 370 m
total distance = 250+175 = 425
