Question

ΚΕ: m.22 2 What is the kinetic energy of 10kg dog running with a velocity of 12m/s?

Answer 1

Answer:

The answer is

720 Joules

Explanation:

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

$K.E = \frac{1}{2} {mv}^{2}$

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

$KE = \frac{1}{2} \times 10 \times {12}^{2} \\ = 5 \times 144 \: \:$

We have the final answer as

720 Joules

Hope this helps you
