1. The problem statement, all variables and given/known data basket ball player throws a ball up in the air and the ball travels 3.2meters before stopping. if the basketball player jumps .5 seconds after throwing the ball. what velocity does he need to reach the ball. 2. Relevant equations vf^2=v1^2+2as sf=si+vot+1/2at^2 vf=vi+aot 3. The attempt at a solution i use vf^2=vo^2+2as to solve for the initial velocity of the ball which i get 7.919 m/s . I solve for the time it takes the ball to reach the max height by using vf=vi+aot and i get .808 seconds. I have no idea had to solve then for the basketball player? Do i use the same method as the ball and if i do; what do i do with the .5 second delay?
