a ball is dropped from a height h, at a polar angle q (measured down from the north pole). how far east is the ball deflected, by the time it hit the ground?

i think they are all correct

explanation:

they seem good

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

find the sum of the two horizontal vectors and the sum of the two vertical vectors
