Two geological field teams are working in a remote area. a global positioning system (gps) tracker at their base camp shows the location of the first team as 37 km away, 21° north of west, and the second team as 32 km away, 38° east of north. when the first team uses its gps to check the position of the second team, what does it give for the second team's (a) distance from them and (b) direction, measured from due east?

distance of 2nd team from 1st team will be:  58.2

Direction of 2nd team from 1st team will be:  14.90 deg North of east

Explanation:

ASSUME Vector is R and  makes angle A with +x-axis,

therefore component of vector R is

From above relation

Assuming base camp as the origin, location of 1st team is

away at 21 deg North of west (North of west is in 2nd quadrant, So x is -ve and y is positive)

location of 2nd team is at

, at 38 deg East of North = 32 km, at 58 deg North of east (North of east is in 1st quadrant, So x and y both are +ve)

Now position of 2nd team with respect to 1st team will be given by:

Using above values:

distance of 2nd team from 1st team will be:

Direction of 2nd team from 1st team will be:

Direction = 14.90 deg North of east

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
