Answer:
9.8 m/s/s
Explanation:
The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

We'll be using the 5 numbers in your question.
In order to solve this problem, we need to know what range is.
The range is the spread of your data from the <u>lowest</u> to the <u>highest</u> value.
In order to find the range, we need to order the values from least to greatest.
Note: No picture of the stem-and-leaf plot is given in the question.
From least to greatest:
2, 5, 14, 19, 32.
Next, find the maximum and the minimum values.
Minimum: 2
Maximum: 32
Lastly, subtract the maximum and the minimum:
32-2=30.
Your range is 30.
