Answer:

Explanation:

Kinetic energy= K.E = (1/2) × mv²

K.E = 0.5× 0.8kg× 100m²/s² = 40 N

The Kinetic energy of soccer is "40 J".

Given values:

Mass,

  • m = 0.8 kg

Velocity,

  • v = 10 m/s

As we know,

→ [tex]Kinetic \ energy (K.E.) = \frac{1}{2} mv^2[/tex]

By substituting the values, we get

                                       [tex]= \frac{1}{2}\times 0.8\times (10)^2[/tex]

                                       [tex]= \frac{1}{2}\times 0.8\times 100[/tex]

                                       [tex]= 0.4\times 100[/tex]

                                       [tex]= 40 \ J[/tex]                                        

Thus the above answer is correct.
