The distance traveled by the student's boxcar that starts from rest and reaches an acceleration and velocity of 13.1 m/s² and 24.5 m/s, respectively, is 22.9 meters.
We can find the distance traveled by the boxcar with the following kinematic equation:
Where:
: is the final velocity = 24.5 m/s
: is the initial velocity = 0 (it starts from rest)
a: is the acceleration = 13.1 m/s²
d: is the distance =?
By solving the above equation for <em>d</em>, we have:
Therefore, the boxcar will travel 22.9 meters.

Answer:
Star system closest to us
Answer:
193.4 J/K
Explanation:
For a closed system, the entropy is given as the natural logarithm of microstates.
The number of particles ( grains of sand ) N = 28
The number of boxes ( compartments ) M = 1000
Entropy is the logarithm of number of microstates
But the number of microstates is given by
