Consider a coin which is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back down again. While the coin is moving upward after being released, what would be its acceleration?
Take up to be the positive direction.
1. The acceleration is in the negative direc-
tion and increasing.
2. The acceleration is in the negative direc-
tion and decreasing
3. The acceleration is in the negative direc-
tion and constant.
4. The acceleration is in the positive direc-
tion and increasing.
5. The acceleration is in the positive direc-
tion and decreasing.
6. The acceleration is zero.
7. The acceleration is in the positive direc-
tion and constant.
