A vector having magnitude 20 added to another vector have magnitude 25 find the magnitude of summight vector

Answer»

tion:|X| = 20 , |y| = 25because [MATH]o \LEQ ||x| - |y|| \leq | x - y| \leq |x + y| \leq |x| + |y|[/math]we only KNOW the magnitude no DIRECTION then it can bebetween [math]|20 - 25| = 5 \leq 45 = 20 + 25[/math]
