The student 2 did the MOST work because he pushed the box to a greater height.
The given parameters:
- <em>Force applied by Student 1 = 500 N</em>
- <em>Height of table for student 1 = 1.2 m</em>
- <em>Height of ramp for student 2 = 5 m</em>
The work done by student 1 is calculated as follows;
Work = P.E = mgh
P.E = 1.2mg
The work done by the student 2 is calculated as;
P.E = 5mg
where;
- <em>m </em><em>is the </em><em>mass </em><em>of the box</em>
Thus, we can conclude that the student 2 did the MOST work.

Answer:
4.5 N upward
Explanation:
You take the net force and subtract it from the weight

The distance covered is 115 m
Explanation:
The motion of Ileana is a uniformly accelerated motion (constant acceleration), therefore we can use the following suvat equation:
where
s is the distance covered
u is the initiaal velocity
v is the final velocity
t is the time elapsed
In this problem, we have:
u = 4.20 m/s
v = 5.00 m/s
t = 25.0 s
Therefore, we can re-arrange the equation to find the distance covered:
