A golfer hits a shot to a green that is elevated 2.0 m above the point where the ball is struck. The ball leaves the club at a speed of 16.0 m/s at an angle of 40.0° above the horizontal, which is the +x axis. It rises in the +y direction to its maximum height and then falls down to the green. Ignore air resistance.

What is the algebraic expression for the y component Vy of a ball's velocity just before landing on the green? Express your answer in terms of the initial launch speed v0, the launch angle above the horizontal, the acceleration ay in the vertical direction, and the vertical displacement y. (Use v_0 for v0, theta for , a_y for ay, and y as necessary.)
Vy=?

You must show your work before we can help you. Do you have any thoughts on the question? Hint: Kinematic equations.
