1. Now, there's a few answers you might have given to answer this question. Let's talk about them.
2. First, you might have used this equation, this definition of acceleration,
3. to say okay well the ball changes its velocity by 20 meters per second by going from 0 to 20,
4. which means Δv is equal to 20 m/sec and since it takes 2 seconds to drop
5. Δt is equal to 2 seconds.
6. Well, this is just the equation for acceleration and so the answer is
7. 20/2 or 10 m/sec square.
8. That's your first answer you may have given, maybe 10 m/sec squared.
