If you double the velocity, the kinetic energy is multipled by 4 New kinetic energy = 4*2400 = 9600J<a href="http://www.telescopebuyingguide.com/bushnell-telescope.htm"> Trevor H</a> The kinetic energy is proportional to the velocity squared.

Answer is 2400 *4 = 9600J<a href="http://www.resumeminers.com/universities/gender-studies-degree.htm"> David W</a> Kinetic energy = 1/2 * mv^2

doubling the speed will result in 2^2 = 4 times increase in KE.
