Projectile Motion and Level Horizontal Range. 1. The problem statement, all variables and given/known data The acceleration of gravity is 32ft/s ^2. If a pitch were thrown horizontally with a velocity of 96.9 mi/h, how far would the ball fall vertically by the time it reached home plate, 60ft away. Answer in units of ft. So speed is 142.12 ft/s. 2. Relevant equations Vx = Vxo + Axt Y= Yo + VyoT + 1/2AyT^2 or Vy^2 = Vyo^2 + 2Ay(Y-Yo) For the second equation, don't know which one to use. 3. The attempt at a solution I got the time it took to reach 60 feet by using the first equation. T= 4.441. I don't know where to go from there. I think I use this equation: Y= Yo + VyoT + 1/2AyT^2 but I'm not sure. Any help would be appreciated greatly. Edit: actually t= .422 seconds.
