Enh, the tech space is very much innovate or die. So yeah, they could probably throw everything in maintenance mode and make a reduced headcount work, but if AWS goes stagnant it’s entirely likely that Amazon goes the way of IBM and Motorol. Especially when someone (likely, Microsoft or Google) comes to take a slice of the AWS market share.
Assuming that’s it’s just the normal force of Earth’s gravity at work on the witch, it’s just a case of working Newton’s second backwards with the gravitational “constant” acceleration ≈ 9.8 m/s²:
F = ma
980 N = m × 9.8 m/s²
980 / 9.8 = (m × 9.8) / 9.8, units omitted for text clarity
100 kg = m
In other words, op is assuming that an average size witch masses approximately 100kg (or about 220 lbs in fingers, knees, and toes units).
