Two balls are launched with the same initial angle. The green ball has an initial velocity twice as large as the red ball's initial velocity. How do their ranges compare?

1. The red ball goes 4 times further
2. The red ball goes twice as far
3. The green ball goes twice as far
4. The green ball goes 4 times further
5. It depends on the ratio of their masses
