An automobile with a mass of 250 kg is moving at a speed of 10 m/s. Do the Kinetic energy calculations?

Kinetic Energy Formula
The energy that a body has, as a result of its motion is known as kinetic energy.

E = ½ mv² 

Where, 

E  Kinetic Energy
m  Mass of the body
v  The velocity with which the body is traveling

Solution to the question,
 

Mass of the body, m = 250 Kg, 

Velocity of it, v = 10 m/s, 

Thus, kinetic energy will manifest as:

E = ½mv² 

E = ½×250×10² 

= 125 ×100 

E = 12500 joules 

The kinetic energy will therefore be 12500 joules.
