A person walks 25m west and then 45m at an angle of 60 degrees north of east. What is the magnitude of the total displacement?

2 answers

North component of resultant: 45 sin 60 = 38.97 m
East component of resultant: 45 cos 60 - 25 = -2.5 m

displacement magnitude
= sqrt[(38.97)^2 + (-2.5)^2]
= 39.05 m

39.05
