.a_{\text{mov}} = a_{\text{fixa}} - a_M \, \sin\alpha

.\delta
as a positive value (it said\delta = \frac{E_{\text{inicial}} - E_{\text{final}}}{E_{\text{inicial}}}
, instead of negative value, which would be correct if the llm said\delta = \frac{E_{\text{final}} - E_{\text{inicial}}}{E_{\text{inicial}}}
. Considering each part valued at10/3=3.33 points
, we could consider only half for part (b) for the mistake.total points: 3.33 * 2 + 3.33/2=8.33
v_{\text{NS}} &= v_0 + v_e
, this is only valid ifm<<M
. Checking the solution, we can see thatv_{\text{NS}} &= v_0 + \frac{M}{M+m} \cdot v_e
, i.e., o1 would be correct only ifm<<M
(which is probably true in real life, but the problem statement does not says that.total points: 5
total points: 10
.total points: 3.33 + 3.33/2 + 3.33=8.33
.\omega
was not given in the problem statement and used it to answer (b). Part (c) was a terrible answer, it expressed\omega
in terms ofF_{\text{resultante}
and then showed this force in terms of\omega
, which is a circular reference.total points: 3.33 + 0 + 0 = 3.33
.total points: 0
.total points: 10
Total points so far:
(10+10+0+8.33+5+10+8.33+3.33+0+10) / 10 = 6.50
