A radar antenna is tracking a satellite orbiting the earth. At a certain time, the radar screen shows the satellite to be 165 km away. The radar antenna is pointing upward at an angle of 55.3° 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.
a) x = 89.7 km, y = 123.8 km
b) x = 123.8 km, y = 89.7 km
c) x = 144.2 km, y = 144.2 km
d) x = 165 km, y = 0 km
