Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?
1) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.
2) The kinetic energy of the ball thrown at 20 meters per second is two times (2Ă—) the kinetic energy of the ball thrown at 10 meters per second.
3) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.
4) The kinetic energy of the ball thrown at 20 meters per second is four times (4Ă—) the kinetic energy of the ball thrown at 10 meters per second.
