Please help me with question 2
1. On a planet whose radius is 1.5 × 107 m, the acceleration due to gravity is 20 m/s². An astronaut with a mass of 60 kg is standing on its surface.
Different situation now. You re out in space, on a rotating wheel-shaped space station of radius 978 m. You feel planted firmly on the floor , due to artificial gravity. The gravity you experience is Earth-normal, that is, g = 9.81 m/s^2. How fast is the space station rotating in order to produce this much artificial gravity? Express your answer in revolutions per minute (rpm). 0.478 rpm 0.956 rpm 0.100 rpm 97.9 rpm
7.) A sateltle orbits at a height of 6,000 km above the earth’s surface. REarth = 6.38 × 106 m, mEarth = 5.98 × 1024 kg. What is the magnitude of the gravitational acceleration g at this height, in m/s2? Use G = 6.67 × 10-11 N·m2/kg2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
1. Gravity: A satellite circles the earth three times per day (it has an 8-hour period). Given Mearth = 5.98x1024 kg, rearth = 6.38x10° km, and G=6.67x10" Nm²/kg², and assuming the orbit is circular, a. Find the radius of the orbit, how many earth radii is it? b. What is the speed of the satellite (in km/s)? c. What is the acceleration due to the Earth's gravity at that radius, i.e. what is "g" at the satellite radius? How much stronger is g at the Earth's surface (what is g/g.t_sat)?
3. Four masses are at the vertices of a square. Find the magnitude of the gravitational force on the mass m1. Given: m1 = 6 kg, m2 = 80 kg, m3 = 80 kg, m4 = 80 kg, r = 24 m. G = 6.674 x 10-11 N•m2/kg2.
The Earth spins at 460 meters per second at the equator. The radius of the Earth is 6.37 x 106 m. A person who believes in a flat Earth says that if the Earth was round and spinning that fast we would all fly off. Imagine if you were standing inside a hollow earth. How much centripetal acceleration would you experience? How does this compare to the acceleration due to gravity we feel at the Earth’s surface? Does it explain why we don’t fly off the Earth due to the spin?
Found a large planet the size of Jupiter orbiting a star. The distance of the planet is 1/9 times the distance between Mercury and the sun. The planet takes 3.09 days to make one orbit (assuming circular). How fast is the planet moving? (Knowing G = 6.67 × 10^-11 N m²/kg², distance of Mercury from the sun = 5.79 x 1010 m) a. 131 km/s b. 141 km/s c. 151 km/s d. 161 km/s e. 171 km/s
4. We are planning a human exploration mission to Mars. We will first place our spacecraft into a circular around Mars and then send down a lander. a) If we want the spacecraft to orbit at an altitude of 170 km above the Martian surface, what will the velocity and orbital period of the spacecraft? b) When we land astronauts on the surface of Mars, what acceleration due to gravity in terms of g's (i.e. as a fraction of the Earth's gravitational acceleration) will the astronauts experience? You are permitted to use an online resource (e.g. Google) to find the necessary information about Mars that you might need in solving this problem.
