a. what is the y coordinate of the target

b.how long does it take for the projectile to hit the target

c.what is the y- component of its velocity just before it impacts the target

d. and what is its velocity ... magnitude and idrection, just before it impacts the target ?

this is what i did

1. drew graph

2.cos60=vox/4m/s

vox=2m/s ; ax=0

3.sin60= voy/4m/s

voy= 3.46 m/s ; ay = -9.8ms2

4.time to travel and hit the target.

1.0/2 = .5 seconds

5. y coordinate you can find the equation with

y=voyT+1/2ayT^2

plugging in what i know, i got .51

im REALLY really confused.. please enlighten me
