A probe was sent to explore an unknown in a galaxy far away. On Earth, the probes mass is 320 kilograms (kg) and it's weight is 3,140 Newtons (N). The gravity of the unknown moon is 0.14 times greater than the gravity of Earth. Which choice below accurately describes how the mass and weight of the probe will change after it lands on the unknown moon?

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
