Question

What is the kinetic energy possessed by a body of mass 5 kg moving with a velocity of 2 m/s?

Answer 1

Answer:

10kgm²s-²

Step-by-step explanation:

kinetic energy= 1/2mv²

=1/2x5x2²

= 1/2x5x4

=1/2x20

=10

Answer 2

Answer:

The kinetic energy possessed by a body of mass 5 kg moving with a velocity of 2 m/s is 10J

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 $m=5kg$

velocity of the body $v=2m/s$

now the kinetic energy of the body

$KE=\frac{1}{2} *5*2^{2}$

⇒$KE=10J$
