1. A baseball is tossed upward with an initial velocity of +24 m/s, rises to some high position, and then falls back down to be caught at its original release position. What is the value of its acceleration immediately after release?

2. A baseball is tossed upward with an initial velocity of +36 m/s, rises to some high position, and then falls back down to be caught at its original release position. What is the value of its acceleration immediately before being caught?

3. A baseball is tossed upward with an initial velocity of +36 m/s, rises to some high position, and then falls back down to be caught at its original release position. What is the value of its acceleration immediately after release?

4. A baseball is tossed upward with an initial velocity of +36 m/s, rises to some high position, and then falls back down to be caught at its original release position. What is the value of its acceleration 4 seconds after release?

5. A baseball is tossed upward with an initial velocity of +36 m/s, rises to some high position, and then falls back down to be caught at its original release position. What is the value of its velocity at its highest point in the air?

ANYTHING helps. Thank you so much!
