Please help!! I need this asap! thank you so much!! <3


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 (2×) 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 (4×) the kinetic energy of the ball thrown at 10 meters per second.
