Question

A baseball pitcher makes a big mistake and throws the ball straight up. If it reaches a maximum height of 15 m find the initial velocity he threw it up with. (17m/s)

Answer 1

 

Vf is the final velocity

 

V0 is the initial velocity

 

S = 15 the distance traveled

 

(Vf)^2 = (V0)^2 + 2 g s

 

(Vf)^2 = 0^2 +2(9.8)(15)

 

(Vf)^2 = 294

 

Vf = 17.1464282....
