In the given graph, the following are the records of the distance of the tennis ball at a certain time (seconds) after being hit:
Time (seconds) Distance (meters)
1 0.5
2 1
3 1.5
4 2
5 2.5
To be able to get the speed of the tennis ball, let's use any of the data (Time and Distance Covered) in the graph, and use the formula in calculating the speed.
![\text{ Speed = }(Dis\tan ce)/(Time)](https://img.qammunity.org/2023/formulas/mathematics/college/fp3v2p7pi2cvu1o1tt92vv4oc0i4znb0m9.png)
Let's use 1 second = 0.5 meter. We get,
![\text{ Speed = }\frac{0.5\text{ meter}}{1\text{ second}}](https://img.qammunity.org/2023/formulas/mathematics/college/2tyvxla14pkd2xlalxvezkd1c8rysy8hus.png)
![\text{Speed = 0.5 meter/second}](https://img.qammunity.org/2023/formulas/mathematics/college/xkb6frctqihn1uj87kv26nhivgj8vcscqp.png)
Therefore, the speed of the tennis ball is 0.5 m/s.
The answer is letter A.
