Question

if A bar =3i-4j and B bar=-i-4j,"calculate "the direction" of A bar+B bar".....particularly I mentioned direction​

Answer 1

Answer:

A full rotation is 360 degrees

It means turning around until you point in the same direction again. ... "Doing a 360" means spinning around completely once (spinning around twice is a "720").

Answer 2
