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