The fastest major league pitcher throws a ball at 45m/s. If he throws the ball horizontally, how far does it drops vertically on the 18.4m trip to the home plate?
time in air: 18.4/45 seconds
distance fell:1/2 g t^2
So why did you used the equation Vx=Vox-gt for time, instead of the equation X= -1/2gt^2 + Voxt + Xo. I used the second one because of they gave me 18.4 which is the distance traveled in the x-axes? thanks!
for time in air i got approx. .40s
