Ah, my mistake.

Your equations are correct (although as I said in my other comment 9.81 is the global average but gravity varies by ~0.1 so that’s too many significant figures), but their issue doesn’t have to do with using sloped distance, by which I assume you mean the length of the slope (they don’t as far as I can tell). It says the height change is 2 meters, and they use 2 meters as the distance since that’s the component of the displacement parallel to gravity. The problem is that they didn’t convert mass to weight.

work = average force • displacement = |average force| * |displacement| * cos(angle between them)
     = component of average force parallel to displacement * |displacement|
     = component of displacement parallel to force * |average force|

weight = force due to gravity = mass * acceleration due to gravity ≈ 5 kg * 9.8 m/s² = 49 N

work = component of displacement parallel to average force * |average force|
     = 2 m * weight
     ≈ 98 Nm

Not quite, you have to multiply distance by the force applied to the object (its weight in Newtons), but they’re using its mass (kilograms).

It’s actually 98 Nm, since weight = mass * gravitational acceleration and g ≈ 9.8 m/s² (you’ll see people give more digits but it actually varies by at most 0.1 m/s² or so depending on where you are).

Is there any reason to use a root account? If you had used sudo for each privilege needing command in stead it would have stopped you.

The alt text doesn’t mention agender.

The first one is incorrect, the limit doesn’t exist unless you specify whether you’re coming from the left or right.

On another note, I think their student has invented a new symbol for “Does Not Exist”.
