A physics student on Planet Exidor throws a ball, and it follows the parabolic trajectory shown in (Figure 1 attached) . The ball's position is shown at 1.0s intervals until t = 3.0 s. At t = 1.0 s the ball's velocity has components vx = 2.6m/s , vy = 3.0m/s .

a) What are the x-y component vectors for t = 0, 2, 3s?
b) What is the g value on Planet Exidor?
c) What was the ball's launch angle?

--
I understand that on Earth horizontal velocity is constant and vertical velocity changes at a constant rate of g. But it's not on Earth so I couldn't find the y-component. I tried finding the net vector for t=1, and I figure I have to use that and vx=2.6m/s in some way but I'm unsure what the next steps are.

Awesome thank you - once I took into account that Vy=0 at t=2, it was easy to go from there.
