A tennis ball rolls off the edge of a tabletop 0.800m above the floor and strikes the floor at a point 1.10m horizontally from the edge of the table.
1) Find the time of flight of the ball.
2) Find the magnitude of the initial velocity of the ball.
3) Find the magnitude of the velocity of the ball just before it strikes the floor.
4) Find the direction of the velocity of the ball just before it strikes the floor.

I will be happy to critique your thinking.
