A ball dropped from rest

How fast is the ball going after 3 seconds?

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

answer; how far out of place which the object finished relative to the starting location;

the components of a vector are the parts of the vectors that are to each other.
