a soccer ball is kicked with an initial velocity of 5.0 m/s in a direction of 30 degrees above the horizontal
a. what are the initial components of the velocity?
b. what are the components of the veloicty just before the ball hits the ground?

  • 11th grade -

    vix = 4.33
    viy = 2.5

    vx = 4.33
    viy = -2.5

    vix= 5 * cos(30)
    viy= 5 * sin (30)

    vx= the same because no force is acting on it
    vy= -viy because nature of parabolic motion and ball is travelling down
