Question

2. Calculate the kinetic energy of a football being launched downfield by Patrick Mahomes. The football has a mass of .5 kg and is thrown at a velocity of 25 m/s. Find the kinetic energy.​

Answer 1

K.E = 156.25 Joules.

Step-by-step explanation:

Given the following data;

Mass = 0.5kg

Velocity = 25 m/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.

Substituting into the equation, we have;

`K.E = (1)/(2)0.5*25^(2)`

`K.E = 0.25 * 625`

K.E = 156.25 Joules.
