Question

The kinetic energy possessed by a body of mass 2 kg and moving with the velocity of 2m/s is​

Answer 1

Answer:

KE-1/2 mv*v

Given;

mass-2kg

velocity-2m/s

KE-1/2*2*2*2

KE-4kgm/s

Answer 2

Answer:

The kinetic energy possessed by a body of mass 2 kg moving with a velocity of 2 m/s is 4J

Explanation:

• The kinetic energy of a particle with mass (m) with velocity (v) is equal to

        $KE=\frac{1}{2}mv^{2}$

From the question, we have

mass of the body $m=2kg$

velocity given  $v=2m/s$

now the kinetic energy of the body

$KE=\frac{1}{2} *2*2^{2}$

⇒$KE=4J$
