You are an astronaut and NASA has asked you to determine how mass and weight change throughout the solar system. They have provided you with a rover with a mass of 227 kg on Earth. What is the rover's mass on the Moon?

Moon's gravity = 1.60 m/s2

363 N

142 N

0.007 kg

227 kg

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
