Question

Which has the greater kinetic energy, an object with a mass of and a velocity of or an object with a mass of and a velocity of ____.

Answer 1

Answer:

Explanation:

Your question is incomplete. I think you want to ask a following question.

Q. Which has greater kinetic energy, an object with a mass of 2.0 kg and a velocity of 1.0 m/s or an object with a mass of 0.1 kg and a velocity of 0.2 m/s.

Ans.

So the object having the greater velocity would have greater kinetic energy.

Let's prove it with the help of formula.

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

Fist case:

$K.E = \frac{1}{2}(2.0)(1.0)^{2}$

$K.E = 1.0 J$

Second case:

$K.E = \frac{1}{2}(1.0)(2.0)^{2}$

$K.E = 2.0 J$
