A football kicker is practicing a field goal ick. THe football (on the ground before it starts) has a initial velocity of 24 m/s at an angle of 40 degrees above the horizontal. The ball flies between two goal posts and hits the right cross bar. The cross bar is 10 ft above the ground. Ignore air resistance.

a) What are the x and y components of the intial velocity b) What is the total flight time of the football c) What is the horizontal distance between the kicker and the crossbar

d) Find the magnitude and direction ( angle relative to a postive x) of the velocity of the football just before it hits the crossbar
