Ah, my mistake.

My pleasure! I wish this community was bigger.

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 opposite angles made by 2 intersecting lines must be equal, so we know that m/3 + 75 = m/2 + 64.

 m/3 + 75  =  m/2 + 64
-m/3         -m/3
       75  =  m/6 + 64
      -64          -64
       11  =  m/6
       ×6      ×6
       66  =  m

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”.
