A ball is shot from the ground into the air. At a height of 0.1m, the velocity is observed to be v=7.7i + 6.4j in meters per second (i horizontal, j upward). What is the direction of the ball's velociry just before it hits the ground?

  • Physics -

    It has the same i component, but j reverses sign.

  • Physics -

    We need to be able to find an angle that it is at when it hits the ground

  • Physics -

    theta = aretan(jomponent/icomponent)
