WebOct 6, 2016 · So, for a problem like this, the first thing to look at is how the apparent weight compares to the actual weight. Student's actual weight : (50 kg) (9.8 m/s 2) = 490 N. Student's apparent weight: 600 N. The student's apparent weight is greater than actual weight, so the acceleration must be UP (positive, as I defined it).
