Question

A 300 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

Answer 1

Answer: 9600 J

Step-by-step explanation:

Answer 2

Answer: 9600 J

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

`K=(1)/(2)mV^(2)`

Where
`m` is the mass of the body and
`V` 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
`m=300kg` and its velocity
`V=8m/s` :

`K=(1)/(2)(300kg)(8m/s)^(2)`

`K=9600J`

Therefore the correct option is B.
