Question
A ship S is moving with a constant velocity (-2.5i + 6j)Km\h. At time 1200, the position vector of S relative to a fixed origin 0 is (16i + 5j) Km.
a) Find the speed of S
Attempt
No idea, there may be a slight irony in me not being able to do a simple vector question as I also wrote a tutorial on them! I have the velocity and the distance moved, how do I use this to determine the speed? Is the speed not the same as the velocity?
