Two dimensional kinematics (component velocity)

[indietro]

Homework Statement

When a problem tells me that the velocity at some h is v=4.13i+6.76j m/s
does that mean that the velocity in xdirection = 4.13 m/s and the velocity in the ydirection = 6.76 m/s. and so are the horizontal and vertical components of velocity constant?

Yes.

... and so are the horizontal and vertical components of velocity constant?

Not necessarily.
