What is the kinetic energy of 10kg dog running with a velocity of 12m/s?

Answer 1

The answer is

720 Joules

Step-by-step explanation:

The kinetic energy of a body can be found by using the formula

`K.E = (1)/(2) {mv}^(2)`

where

m is the mass

v is the velocity / speed

From the question

mass = 10 kg

velocity = 12 m/s

Substitute the values into the above formula and solve

That's

`KE = (1)/(2) * 10 * {12}^(2) \\ = 5 * 144 \: \:`

We have the final answer as

720 Joules

Hope this helps you
