Projectile Motion (Baseball Question)

[skateraXIX]

So I've been having trouble with a problem dealing with projectile motion.

Here's the question:

How much will a ball drop if a pitcher throws the ball horizontally with a speed of 36.5 m/s, from 18m away? (Assuming no spin has been imparted on the ball.)

I'm not sure where to even start at and am really stumped.

You need to use the SUVAT equations (google them). For projectile motion question you can break it into 2 parts horizontal and vertical. The horizontal time needs to be calculated using v=s/t, then you need to work out how much gravity pulls it down in that time. g = 9.81ms^-2.

Awesome I figured it out. Thanks.

v=d/t
36.5=18/t
Divide 18 by 36.5= 0.493

(v1+v2)/2= (0+4.831)/2= 2.416

Here's how I got the v1 and v2:
v1= 0
v2= g x t
v2= 9.8m/s x 0.493= 4.831

Finally:

d=v x t
d=2.416 x 0.493
d= 1.191 m
