A ball is dropped from a tall building
What is its acceleration
What does the acceleration tell us about the velocity of the ball
i believe its was 9.8 mph persec
by gravity its going to far at a rate of 9.8 per sec you can drop basicly anything down a building and it will still fall the same speed. well basicly gravity
acceleration is 9.8 m/s^2 (!),
Acceleration shows how the speed changed during the 1 second of accelerated motion
