This is a uniform rectilinear motion (MRU) exercise.
To start solving this exercise, we obtain the following data:
<h3><u>DATA:</u></h3>- V = 3.8 m/s
- D = ¿?
- T = 15 sec
To calculate the distance, multiply the speed by the time.
We apply the following formula: d = v * t
We clear our data in the formula:
The baseball in 15 seconds will roll a distance of 57 meters.

The lists from greatest to lowest change in velocity.Dustin → Diego → Kira. Option A is correct.
<h3 /><h3>What is acceleration?</h3>The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The acceleration is obtained one by one from the given data as the ratio of the velocity to the time.
For the acceleration of each, you can refer to the excel table attached below.
The velocity changes are listed from largest to least. Dustin and Diego Kira.
Hence, option A is the right answer.
