The kinetic energy of the ball is given by:
where m=5 kg is the mass of the ball and v=2 m/s is its speed. Substituting these numbers, we find the kinetic energy:
Answer:
nice!!! but did you know that geico can save you 15% or more on car insurance!
Explanation:
In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235.
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.
A mechanical wave must have a medium.

The velocity is 60 because you divide your distance by your time (240÷4=60)
