a ball is kicked towards goal posts from a position 20m from and directly in front of the posts. the ball takes 0.60m from the time it is kicked to pass over the cross bar, 2.5m above the ground. the ball is at its maximum height as it passes over the cross bar. you may ignore air resistance.
a)calculate the ball's horizontal component of velocity
b) calculate the vertical component of the velocity of the ball immediately after it is kicked
c) determine the magnitude of the initial velocity of the ball immediately after it is kicked
d) determine the angle above the horizontal at which the ball is kicked
