Another way of representing vectors is i, j, k notation. I, j,
k notation is a fancy way of representing the x, y, and z components
(respectively) of a vector. For instance, 5m East is the same as
5mi, or 6m South is the same as -6mj.
What is the i,j,k notation for a 4m vector that is going at 140°?
Components:
x component : 4m cos 140° = -3.064m
y component : 4m sin 140° = 2.571m
The answer in i, j, k notation is <-3.064mi + 2.571mj>
The next section deals with
horizontal motion.
