Tennis Ball projectile

Click on the yellow tennis ball in the clip on the left. (In the first frame, it is barely visible on the right.) Each time you click on the graph, a data point will be recorded in the video space and be displayed in the graphs and table below. The video will then advance to the next frame. Keep clicking on the ball in each frame until you reach the end of the clip, and then use the graphs and data to answer the questions below. (Unchecking the 'Advance time' button will allow you to edit a time without moving on to the next frame.) Help with VideoPAD.

Questions:
How does the ball move in the horizontal direction?
Constant velocity
Constant (non-zero) acceleration
Changing acceleration
How does it move in the vertical direction?
Constant velocity
Constant (non-zero) acceleration
Changing acceleration
Try to find the horizontal velocity of the ball.
m/s
Try to find the initial vertical velocity and the acceleration in the vertical direction.
m/s
m/s2
Use that information to write two equations of motion describing the horizontal and vertical motion of the ball.
x = m
y = m
