Question: An astronaut exploring an atmosphere - less moon that has a gravitational acceleration of 0 . 5 0 m s 2 makes a controlled fall

An astronaut exploring an atmosphere-less moon that has a gravitational acceleration of 0.50 m s 2 makes a controlled fall (v=0) from a spacecraft hovering stationary at approximately 2.0 x 103 meters. How long does take for the astronaut to reach the surface? What is the astronauts final velocity?
