Answer to Question #17623 in Mechanics | Relativity for Kyle Smith
Question #17623
A person walks 49 m East and then walks 30 m at an angle 49 degrees North of East.
What is the magnitude of the total displacement?
What is the magnitude of the total displacement?
Expert's answer
According to the law of cosines:
a = √(b² + c² - 2*b*c*cos(α)) = √(49² + 30² - 2*49*30*cos(180° - 49°)) = 72.317 m.
a = √(b² + c² - 2*b*c*cos(α)) = √(49² + 30² - 2*49*30*cos(180° - 49°)) = 72.317 m.
