You spike a volleyball with a mass of 0.260 kg. The ball leaves your hand with a speed of 31.29 m/s.The ball has _ energy. Calculate it

Respuesta :

Answer:

as you spike the volleyball, you transfer kinetic energy to the volleyball.

the formula for kinetic energy is as such: [tex]E_{k} = \frac{1}{2}(m)(v^{2} )[/tex], where [tex]E_{k}[/tex] is kinetic energy, m is mass (in kg) and v is velocity/speed in m/s

 [tex]E_{k} = \frac{1}{2} (0.260) (31.29^{2} ) \\ = 127 Joules (3 s.f.)[/tex]
