A projectile is fired through the air. It is launched from the ground, and travels without interference from wind or air resistance, landing on a raised platform above the field. Compare the following values:

1-Initial speed vs. final speed:
2-Initial vertical velocity vs. final vertical velocity:
3-Initial horizontal velocity vs. final horizontal velocity:
4-Initial acceleration vs. final acceleration:
