Question

Distance-Time Grapfoss Object ng Constant Speed - 9) Achillwit and string a speed The graph above shows the Giant the ball towed from starting pucat in 5 seconds.

Answer 1

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)`

Let's use 1 second = 0.5 meter. We get,

`\text{ Speed = }\frac{0.5\text{ meter}}{1\text{ second}}`
`\text{Speed = 0.5 meter/second}`

Therefore, the speed of the tennis ball is 0.5 m/s.

The answer is letter A.
