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=1.60ms2   A. 142 N B. 227 kg C. 0.007 kg D. 363 N

3. The gravitational acceleration at Earth's surface (ga) is about 10 m/s? and ge = GM/R2. What is g, at the surface of a planet with 2X Earth's mass and 3X Earth's radius?

An intergalactic spaceship arrives at a distant planet that rotates on its axis with a period of T = 31 hours. The mass of the planet is M = 2.1 • 1025 kg. The spaceship enters a circular orbit with an orbital period that is equal to the planet's period for the rotation about its axis, T.   a.  Enter an expression for the radius of the spaceship’s orbit.  b.  Calculate the orbital radius in meters.

You are an astronaut on a rotating space station. Your station has an inside diameter of 3.00 km a) Draw a system diagram and FBD of your body as you stand on the interior surface of the station  b) Determine the speed you need to have if your apparent weight is to be equal in magnitude to your Earth -boundweight.  c) Determine your frequency of rotation, both in hertz and in revolutions per minute.

An astronaut weighing 236 lbs on Earth is on a mission to the Moon and Mars.   a.What would he weigh in newtons when he is on the Moon? The acceleration due to gravity on the Moon is one-sixth that on Earth?   b. How much would he weigh in newtons when he is on Mars, where the acceleration due to gravity is 0.38 times that on Earth?   c. What is his mass in kilograms on Earth?

Task 1: Gravitational Fields 1. A person with a mass of 60 kg is inside a rocket that is moving straight up, away from the earth's surface. The radius of the earth is 6.38 x 105 m and the mass of the earth is 5.98 x 1024 kg. a. Find the force of gravity acting on the person at an altitude of 300 000 m. b. Find the altitude that will cause the person's weight to drop to one-quarter of its value on the earth's surface. 2. Mass 1 is four times as large as mass 2. Both masses are at rest and are separated by 200 m. Where could you place a third mass, mass 3, if the net force on 3 must be zero?

22. The drawing represents two suspended spheres. The force of gravity between the two spheres is 12 N (newtons). If the mass of each sphere is doubled (2x),and the distance between the spheres remains constant, what will happen to the force of gravity?A. The force of gravity will decrease by one­half .B. The force of gravity will decrease by one­fourth .C. The force of gravity will increase by a factor of two (2x).D. The force of gravity will increase by a factor of four (4x).

7. A 70 kg astronaut orbits the moon at a distance of 7.2 x 10° m from its center. (Mass of moon = 7.35 x 10²² kg) a. What is the force acting on the astronaut by the moon? b. How fast is the astronaut orbiting around the moon?
