Answer:

900 j

Step-by-step explanation:

KE=1/2mv^2

so:

1/2x(2kg)x(30m/s)^2

is 900 joules. :)

The kinetic energy should be900 j

Given that,

  • You serve a volleyball with a mass of 2 kg.
  • The ball leaves your hand with a speed of 30 m/s.

Based on the above information, the calculation is as follows:

[tex]KE=1\div 2mv^2\\\\\\= 1\div 2\times (2kg)\times (30m/s)^2[/tex]

= 900 joules.
