Question

calculate the the energy of the body of mass 20 kg moving with velocity 0.1m/s

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :
$energy = \frac{1}{2} m {v}^{2}$


Mass m of body = 20 kg

Velocity v of body = 0.1 m/ s


Energy of body

$= \frac{1}{2} \times 20 \times {(0.1)}^{2}$

$= 10 \times 0.01$


$= 0.1$



Therefore, energy of body = 0.1 J

Answer 2

Hey friend,Harish here.

Here is your answer.
___________________________________________________

$Mass(m)= 20Kg$     (given)

$Velocity(v)= 0.1 m/s$  (given)

[tex]Energy = \frac{1}{2} mv^{2} [/tex]
 
            [tex]= \frac{1}{2} (20) (0.1)^{2} [/tex]
 
            [tex]=10 (0.01) [/tex]

            $=0.1 J$
