a 1.0kg ball is thrown into the air with initial velocity of 30 m/s, How much is the kinetic energy

Sagot :

  • Mass=1kg
  • Velocity=30m/s

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

[tex]\\ \sf\longmapsto K.E=\dfrac{1}{2}1(30)^2[/tex]

[tex]\\ \sf\longmapsto K.E=\dfrac{900}{2}[/tex]

[tex]\\ \sf\longmapsto K.E=450J[/tex]
