Question

Vector v has a magnitude of 80 and a direction θ = 60°. What are the magnitude and direction of 4v?

Answer 1

for this case we have the following information:

magnitude =80

direction = 60º

Then we want to find the magnitude and the direction of 4v so we have this:

4v= 320

And the direction is the same 60º then the answer is:

320, 60º
