Explanation / Answer

As the ball leaves the racqutet has avelocity V made up of 2 components: vertical Vv andhorizontal Vh. Vh = V cos() Vv = V sin() The horizontal componentVh remains constant is air resisnce isignored. The vertical component is a subject togravitational acceleration g and Vv = gt The ball wil go up height h2 and over the net then continue movinghorizontally and down to hit the ground h = h1 +h2 h1 - heigh above th eground andpoint of racquet/baal impact h2 -height above theh1 h - maximum height above the tenniscourt. It will take time t1 to get to themaximum height t1= Vv/g h1= 0.5gt12 the time the ball wil lhit the ground is t2 t2= (2h/g) The ball will remain in the air time t t= t1 + t2 From the impact point to the other side of the court the ballwill travel the disnce S or have a range S such as S=Vh t = Vcos() t This is it. t1= Vv/g h1= 0.5gt12 the time the ball wil lhit the ground is t2 t2= (2h/g) The ball will remain in the air time t t= t1 + t2 From the impact point to the other side of the court the ballwill travel the disnce S or have a range S such as S=Vh t = Vcos() t This is it.
