n astronaut is doing a repair work on a space station. Suddenly, he loses his grip and finds himself drifting away from the space station. In less than an hour, because of oxygen depletion, he will simply be…DEAD! What can he do so he can return safely to the space station? Explain using Newton's Laws of Motion.

Your spaceship lands on an unknown planet. To determine the characteristics of this planet, you drop a wrench from 3.00 m above the ground and measure that it hits the ground 0.814 s later. a) What is the acceleration of gravity near the surface of this planet? b) Assuming that the planet has the same density as that of earth (5500 kg/m^3), what is the radius of the planet?

(a) What is the acceleration (in m/s2) of gravity on the surface of the moon? m/s2 (b) What is the acceleration (in m/s2) of gravity on the surface (or outer limit) of Mars? The mass of Mars is 6.42 × 1023 kg and its radius is 3.37 x 106 m. m/s2

A body with a mass of 10.0 kg is assumed to be in Earth's gravitational field with g 9. 80 m/s². What is the net force on the body if there are no other external forces acting on the object?

A 66kg student travels to Mars! You may enter answers in scientific notation as shown: 1.23 x 105 = 1.23e5 What is her weight on earth? Fill out each quantity for the interaction between the student and Mars: G = N/m Mars data mass: 7.39 x 1023 kg radius: 3.39 x 106 m M = 257 kg earth data mass: 5.97 x 1024kg radius: 6.37 x 106m m = 60 kg 3.39 What is her weight on Mars? check answers cannot be deteri

The acceleration due to gravity on Venus is 0.89 that of Earth. a) If the radius of Venus is 6.05 x 106 m, what is Venus’ mass? b) How does this compare to Earth’s mass? c) If you were on a diet and had to “weigh in,” would you rather stand on a scale on Venus or on Earth in order to appear as if you had lost the most weight?

You are on a deep space mission to search for Earth-like planets. Your crew locates a possibleplanet and with scanners find the radius to be 7.5 x 106 m. A team lands on the surface. There,they hang a 1.0 kg mass from a spring scale. It reads 8.5 N. a) Determine the mass of the planet using Newton’s Law of Universal Gravitation. b) Describe whether an astronaut standing on this new planet weighs more, less, orthe same as on Earth. Show your work.

Suppose an astronaut has landed on Mars. Fully equipped, the astronaut has a mass of 132 kg. The acceleration due to gravity on Mars is 0.39 m/s2. What is the weight of the astronaut on Mars?

What is the gravitational force acting on a person due to another person standing 3 meters away. each individual has 50kg of mass.  Help. I do not know how to start this.
