a. what is the y coordinate of the target

b. what was its intial velocity

c.what is the y- components of it s velocity just before it impacts the target

d. and what is its velocity magnitude and direction just before it impacts the target.

what i did:

1. drew graph

2. vy^2+2ay(y-y0) to find initial velocity

vy0= 2.8 m/s

3. find time

with vy=vy0+at

0-2.8/-9.8=.285 seconds

4. y coordinate:

y=voy+1/2at^2

.399

idk how to find the others... please help me.
