Question

Calculate the kinetic energy of an object with mass 10 kg and moving with a velocity of 20m/s

Answer 1

Explanation:

K.E=1/2mv^2

=1/2(10)(20)^2

=1/2(10)(400)

=(10)(200)

=2000J

Answer 2

Answer:

The kinetic energy of an object with a mass of 10 kg and moving with a velocity of 20m/s is 2000J

Explanation:

The kinetic energy of an object with mass (m) moving with velocity (v) is given by the formula

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

From the given question, we have

mass of the moving body $m=10kg$

the velocity of the body $v=20m/s$

put the values in the above equation

we get the kinetic energy of the body $KE=\frac{1}{2}*10*20^{2}=2000J$
