Kinetic energy:

$\overline{){\mathbf{K}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{2}}{\mathbf{m}}{{\mathbf{v}}}^{{\mathbf{2}}}}$

where m is the mass and v is the velocity.

K_{runner} = (1/2)(60)(11^{2}) = 3630 J

A 60 kg runner in a sprint moves at 11 m/s. A 60 kg cheetah in a sprint moves at 33 m/s.

By what factor does the kinetic energy of the cheetah exceed that of the human runner?
