- The acceleration and velocity arrows are straight up.
- The ball isn't accelerating, so we know there is only a velocity vector.
- The ball is getting slower, so the acceleration and velocity vector arrows must be opposite.
- The velocity vector arrow is in the direction of movement. The acceleration vector arrow is pointing downwards.
