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=

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
