Question
a field goal kicker kicks a field goal in football game. Kicker kicks ball from the ground. Foodball has initial speedof 25 m/s when it leaves the ground. Initial velocity hascertain angle above horizontal. Football has mass of 450g When the ball falls down, it reaches a fan sitting in a seat15m above ground behind goal posts What is KE of football when fan catches ball What is speed of ball when it reaches fan If ball stops in fan's hand in .2 s what is magnitude ofaverage force that ball exerts on fan's hand? a field goal kicker kicks a field goal in football game.

Final K.E =intial K.E-loss due to gravity K.E final =0.225*25*25-4.5*15 =73.125J speed of ball =(73.125*2/0.45) =18.03m/s F*0.2 =0.45*18.03 =40.562N
