Sagot :

[tex]{\fcolorbox{white}{lightgreen}{\bf{\textcircled{$\checkmark$}}{Verified\:answer}}}[/tex]

  • Mass of ball=m=5kg
  • Kinetic energy=KE=100J
  • Velocity=v=?

We know

[tex]\boxed{\sf K.E=\dfrac{1}{2}mv^2}[/tex]

[tex]\\ \sf\longmapsto 100J=\dfrac{1}{2}5\times v^2[/tex]

[tex]\\ \sf\longmapsto v^2=100\times \dfrac{2}{5}[/tex]

[tex]\\ \sf\longmapsto v^2=20(2)[/tex]

[tex]\\ \sf\longmapsto v^2=40[/tex]

[tex]\\ \sf\longmapsto v=\sqrt{40}[/tex]

[tex]\\ \sf\longmapsto v=6.2m/s[/tex]
