Garnet punch Amethist so hard that it catch fire. Now, a quickly search for google says that the Volley Ball's rod has a height of around 1 m

- Rod height = 20 px = 1 m
- Panel height = 810 px
- Angle = 0.0234 rad = 1.3406 degrees
- Distance = 854.74 px = 42.737 m
The speed to catch fire is the same as orbital speed, around Mach 23 = 7902 m/s
- Acceleration = 7902^2/(2*42.737) = 730533.31 m/s^2
- Now this is the hard part: I have no weight for Amethyst; however, one of the twins was capable to move her around the sand with no problem, so according to our system it would be, at much, 50 kg: Force = 50*730533.31 = 36526665.42 N = 3727.21 tons (Class M)
Calc would be a Low-End since it consider that Amy reached that speed when hit the ground that isn't exactly the case; however, it use a inflated weight for Amy, for that neutralize the low-end for now.
