<span>Acceleration of ball (a) = 9.8 m/s^2
Speed (v) = 24.5 m/s
Time (t) = Acceleration / Time
= v / a
= 24.5/9.8
= 2.5 s
So it will take 2.5 seconds to reach that speed.</span>

.............………
The student's average speed for the dash was 8.2 m/s. It's not possible to completely describe the student's velocity, because there's no information to tell us what direction she ran.
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.
