5. A cheetah with a mass of 70 kg was clocked running at 72 mph (32 m's). How many joules of
kinetic energy did the cheetah have?

Answer:

Kinetic energy = 35840 Joules

Explanation:

Given the following data;

Mass = 70kg

Velocity = 32m/s

To find the kinetic energy;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where, K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Substituting into the equation, we have;

[tex] K.E = \frac{1}{2}*70*32^{2}[/tex]

[tex] K.E = \frac{1}{2}*70*1024[/tex]

[tex] K.E = 35 * 1024 [/tex]

K.E = 35840 Joules.

Therefore, the kinetic energy possessed by the cheetah is 35840 Joules.
