Question

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 1

Kinetic energy = 35840 Joules

Step-by-step 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;

`K.E = (1)/(2)MV^(2)`

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

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

`K.E = (1)/(2)MV^(2)`

Substituting into the equation, we have;

`K.E = (1)/(2)*70*32^(2)`

`K.E = (1)/(2)*70*1024`

`K.E = 35 * 1024`

K.E = 35840 Joules.

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