A60 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?

Explanation:

It is given that,

Mass of the runner, m₁ = 60 kg

Speed of runner, v₁ = 11 m/s

Mass of cheetah, m₂ = 60 kg

Speed of cheetah, v₂ = 33 m/s

Kinetic energy of runner,

........(1)

Kinetic energy of cheetah,

..............(2)

From equation (1) and (2), it is clear that

So, the kinetic energy of the cheetah is nine times that of human runner. Hence, this is the required solution.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
