Finding launch angel from velocities

  1. Sep 20, 2013 #1
    I'm having troubling finding a launch angel from a set of given velocities.

    v=2[itex]\hat{i}[/itex], 4[itex]\hat{j}[/itex] at t=0

    v=2[itex]\hat{i}[/itex], 2[itex]\hat{j}[/itex] at t=1

    v=2[itex]\hat{i}[/itex] at t=2

    v=2[itex]\hat{i}[/itex], -2[itex]\hat{j}[/itex] at t=3

    the g=-2 on this planet

    Thanks for the welcome!

    got it, i'm still a bit shaky with vectors.
