Answer:

Yes, Roberto will have twice the kinetic energy

Step-by-step explanation:

The equation for kinetic energy is Ke = 1/2(m)v^2

The variable m is not squared by anything, which means it is directly proportional to the equation. If you were to multiply m by 2, it would in turn multiply the entire equation by 2, getting you an outcome with twice as much kinetic energy.
