Time to reach the peak (t)=6.25/2=3.125s 

When the ball reaches to peak point, the final velocity will be zero. v=0m/s .

Here, the acceleration of ball is a=−g=−9.8m/s 2  

"u" is the initial velocity of the baseball. 

Using v=u+at, 

0=u+(−9.8)(3.125) 

u=30.625m/s 

"h"  is the height reached by ball. 

 Using v2−u2=2ah 

02 −(30.625)2=2(−9.8)h 

 h=47.85m
