Vector V represents a displacement of 120 km at 29.0 degrees counterclockwise from the x axis. Write V in unit vector notation.

Question

Express your answer using three significant figures.

V= _______ km

i know the answer should be Vx=120cos29 and Vy=120sin29 but the question requires the answer to be in form such that the answer includes variable i with an ^ above it. How do i do that?

Answer 1

having the same problem

Answer 2

shortcut: \hat

Answer 3

If your using mastering physics it goes like this 105i+58.2j with the ^ over them.
