A300 kg buffalo runs across the prairie with a speed of 8 m/s. what is the kinetic energy of the buffalo? a: 19,200 j b: 9600 j c: 4800 j d: 1200 j

The kinetic energy  of a body is that energy it possesses due to its movement and is defined as:

Where is the mass of the body and its velocity .

This has to do with the speed of an object and how much mass it has; basically how the object is moving.

Now, according to this equation and knowing that the mass of the buffalo is  and its velocity :

Therefore the correct option is B.

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange
