Sonic vs The Average Hedgehog

One of the world's favorite characters is Sonic the Hedgehog, a blue hedgehog who runs incredibly fast. Sonic can run at around Mach 15, which is 5,104.4 m/s (11,509 MPH). That is incredibly fast! He also weighs about 34.93 kg, which means that at full speed, his kinetic energy is about 455,048,817.3 J.

If a normal hedgehog which weighs about 0.91 kg, were to run at its top speed of 5.3 m/s, its kinetic energy would be around 12.8 J. This is about 0.000003% of the energy that Sonic generates.
