Question

For each of the following velocity vectors, give the vector component, the scalar component, and the magnitude. (a) v = 48.0j m/s (i) vector component (Express your answer in vector form.)

Answer 1

Obtaining the component part of the letter 'i' warns that it is the velocity is oriented on the X axis. At the same time the numeric part, in this particular case will represent the scalar part and therefore the magnitude of the vector.

The velocity is

$\vec{v} = 48.0\hat{i} \text{ m/s }$

The vector component of the velocity is

$v_x = 48.0m/s$

The scalar component of the velocity is

$v = 48.0m/s$

The magnitude of the velocity is

$v = 48.0m/s$
