Answer to Question #73207 in Classical Mechanics for Antoinette Maqueda
A delivery truck travels 21 blocks north, 16 blocks east, and 26 blocks south. What is its final displacement from the origin? Assume the blocks are equal length.
The magnitude of displacement is
d=√(〖16〗^2+(-5)^2 )=17 blocks.
The direction is
θ=tan^(-1)〖5/16〗=17° east of south.
