A racket ball is struck in such a way that it leaves the racket with a speed of 4.87m/s in the horizontal direction. When the ball hits the court, it is a horizontal distance of 1.95m from the racket. Find the height of the racket ball when it left the racket. I'm not sure what equation to use for this.

Hi. I have to finish my introduction to an investigation I will be doing, finding the relationship between heights and weights amongst school pupils..

However I am now chosing my second hypothesis (e.g 16 yr old males are taller and heavier than 12 year old females).. But I have to incorporate advanced statistical methods into it, to get the higher grade.. What should I say??

Thanks in advance
