Aradar antenna is tracking a satellite orbiting the earth. at a certain time, the radar screen shows the satellite to be 118 km away. the radar antenna is pointing upward at an angle of 58.9° above the ground. find (a) the x and (b) the y components (in km) of the position vector of the satellite, relative to the antenna.

x component 60.85 m

y component 101.031 m

Explanation:

We have given distance r = 118 km

Angle which makes from ground = 58.9°

(a) X component of distance  is given by

(b) Y component of distance is given by

These are the x and y component of position vector
