A baseball has a mass of 0.145 kg and is 12 m above the ground. If it is moving, what is its speed?

A. 17 m/s
B. 35 m/s
C. 89 m/s
D. 130 m/s



Answer :

To determine the correct velocity at which the baseball is moving, let's analyze the given parameters and the possible velocities provided. We have the following:

- Mass of the baseball: [tex]\(0.145 \, \text{kg}\)[/tex]
- Height above the ground: [tex]\(12 \, \text{m}\)[/tex]
- Possible velocities: [tex]\(17 \, \text{m/s}\)[/tex], [tex]\(35 \, \text{m/s}\)[/tex], [tex]\(89 \, \text{m/s}\)[/tex], [tex]\(130 \, \text{m/s}\)[/tex]

The fact that the baseball can be moving with different velocities suggests we are asked to identify which of the provided velocities apply to the baseball's movement. Here are the velocities:

1. [tex]\(17 \, \text{m/s}\)[/tex]
2. [tex]\(35 \, \text{m/s}\)[/tex]
3. [tex]\(89 \, \text{m/s}\)[/tex]
4. [tex]\(130 \, \text{m/s}\)[/tex]

Let's list them out:

1. A velocity of [tex]\(17 \, \text{m/s}\)[/tex] is plausible for a baseball that is thrown by an average player.
2. A velocity of [tex]\(35 \, \text{m/s}\)[/tex] is quite high, indicating the baseball is moving relatively fast, potentially hit or pitched by a skilled player.
3. A velocity of [tex]\(89 \, \text{m/s}\)[/tex] would typically be associated with a baseball hit by a professional player during a strong hit.
4. A velocity of [tex]\(130 \, \text{m/s}\)[/tex] is exceptionally high, possibly representing a very powerful hit or throw, closer to the upper limits of what a baseball can achieve in professional settings.

Given the possible options, the correct answer would be all the velocities [tex]\(17 \, \text{m/s}\)[/tex], [tex]\(35 \, \text{m/s}\)[/tex], [tex]\(89 \, \text{m/s}\)[/tex], and [tex]\(130 \, \text{m/s}\)[/tex]. These are all valid velocities at which the baseball can be moving under different circumstances. Hence, the baseball could be moving at any of these velocities depending on specific conditions.

The possible correct velocities are:

[tex]\[ [17, 35, 89, 130] \, \text{m/s} \][/tex]
