An astronaut in an experimental high speed spacecraft flies a mission several decades in the future. when the astronaut returns from his mission, instruments on board the spacecraft show that the elapsed time of the mission was 17.154 hours. however, in mission control, the elapsed time for the mission was 17.852 hours. how fast was the spacecraft moving?

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
