You serve a volleyball with a mass of 0.77 kg. The ball leaves your hand with a velocity of
2.33 m/s. Calculate the joules of kinetic energy of the ball.

Respuesta :

Given :

  • mass (m) = 0.77 kg

  • velocity (v) = 2.33 m/s

Solution :

[tex] \boxed{ \mathrm{Kinetic \: Energy = \frac{1}{2} m {v}^{2} }}[/tex]

  • [tex] \dfrac{1}{2} \times 0.77 \times (2.33) {}^{2} [/tex]

  • [tex] \dfrac{418.0253}{2} [/tex]

  • [tex]209.01265 \: \: joules[/tex]

  • [tex] \mathrm{209.01 \: \: joules} \: \: \: (approx)[/tex]
