4 10 points You send a flash of light toward the Moon. It bounces off a mirror and returns to you. You measure the time between when you sent the flash and when it returns to you and find that the whole process took 2.0 seconds.

Calculate how long it would take the Earth to fall into the Sun if its orbital motion were stopped. Then, instead of the Earth, imagine a second 1 solar mass star orbiting the Sun. Start with the equations of motion and calculate how long it would take for the two stars to crash into each other.

1. If Ben continued working until he
turned 64, would he be able to claim Social Security `benefits, and
if so, what percentage of his full benefit would he receive?
2. If Ben was in an accident and
passed away before retiring, would his wife receive any Social
Security benefits? Why or why not?
3. Ben is enrolled in a defined
