When speed slows down you have kinetic energy.
I don’t know just needed points im sorry
<span>A phase change is an example of a
Physial change</span>
<span>How much kinetic energy does a 7.2-kg dog need to make a vertical jump of 1.2 m?
</span>Answer:
85 Joule (approx)
Explanation:
Potential energy at highest point
<span><span>P.E = mgh = 7.2 kg × 9.8 m/s2</span>×1.2 m≈85 Joule</span>
This is the kinetic energy required for dog to jump a height of 1.2 m.
hope this helps!
