Question
a caribu trecks 125m at 35 degrees west of south, and then 105m west. what is the caribus resultant displacement

break up the vectors into NSEW
displacement= 125@35WofS + 105W
= 125sin35 W + 125cos35 S + 105W
then add the W components, and use the displacement theorum
displacement=sqrt(Wdistance^2+Sdistance^2)
at an angle of arctan Westdistance/Sdisance West of South
displacement= 125@35WofS + 105W
= 125sin35 W + 125cos35 S + 105W
then add the W components, and use the displacement theorum
displacement=sqrt(Wdistance^2+Sdistance^2)
at an angle of arctan Westdistance/Sdisance West of South
