Question

If a baseball pitch was thrown horizontally and the ball falls .809m by the time it reaches home plate 18.3 m away how fast was the pitch? the time of flight? Calculate the initial horizontal velocity.

Answer 1

Get time of flight from the fall h:
h = gt^2/2 ==> t = sqrt(2h/g)
Speed of pitch = initial hor. velocity = hor. distance / t
