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?
vix=
viy=
b. what are the components of the veloicty just before the ball hits the ground?
vx=
vy=

  • 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
