Question

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

Answer 1

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

the formula for kinetic energy is as such:
`E_(k) = (1)/(2)(m)(v^(2) )`, where
`E_(k)` is kinetic energy, m is mass (in kg) and v is velocity/speed in m/s

`E_(k) = (1)/(2) (0.260) (31.29^(2) ) \\ = 127 Joules (3 s.f.)`
