A soccer ball is hit vertically upward by a player. What is its acceleration after 1 second?

1. Break Down the Problem

The question asks for the acceleration of a soccer ball after 1 second of being hit vertically upward.

2. Relevant Concepts

In a vacuum (ignoring air resistance), the only force acting on the soccer ball after it has been kicked upwards is gravity.

• The acceleration due to gravity ($g$) is approximately $9.81 \, \text{m/s}^2$ downward.

3. Analysis and Detail

From the moment the soccer ball is hit, it will experience an upward velocity, but gravity will continuously act on it, pulling it back down.

Regardless of how high it rises, the acceleration remains constant due to gravity.

4. Verify and Summarize

Since the acceleration due to gravity is a constant $9.81 \, \text{m/s}^2$ downward, the soccer ball’s acceleration after 1 second is still $9.81 \, \text{m/s}^2$.

Final Answer

The acceleration of the soccer ball after 1 second is $9.81 \, \text{m/s}^2$ downward.
