Question

The cheetah is the fastest land animal, reaching speeds as high as 33 m/s, or roughly 75 mph. What is the kinetic energy of a 65 kg cheetah running at top speed? Express your answer in SI units.

Answer 1

Ek= 35.392 kJ or 35.392 10³ J

Step-by-step explanation:

Formula for Kinetic energy:

Ek=
`(1)/(2)` × m ×
`v^(2)`

since m= 65kg and v= 33m/s

Ek=
`(1)/(2)`× 65×
`33^(2)`

Ek= 35.392 kJ or 35.392 10³ J
