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

Answer:

Ek= 35.392 kJ or 35.392 10³ J

Explanation:

Formula for Kinetic energy:

Ek= $\frac{1}{2}$ × m × $v^{2}$

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

Ek= $\frac{1}{2}$× 65×$33^{2}$

Ek= 35.392 kJ or 35.392 10³ J
