The mean diameters of Mars and Earth are 6.9 * 103 km and 1.3 * 104 km, respectively. The mass of Mars is 0.11 times Earth’s mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b)What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?
The gravitational constant g is 9.807 m/s² at sea level, but it decreases as you go up in elevation. A useful equation for this
decrease in g is g = a - bz, where z is the elevation
above sea level, a = 9.807 m/s², and b = 3.32 × 10−6 1/s². An astronaut "weighs” 80.0 kg at sea level. [Technically this means that
his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z = 355 km). If
the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the
satellite stopped moving?
The person's weight in N while floating around in the International Space Station is
The astronaut feels a gravitational acceleration of 692.928 m/s²
8.6616 N.
The mean diameters of X and Y, two planets in the same solar system, are 6.5 x 10³ km and 1.2 x 104 km, respectively. The mass of x is 0.21 times the mass of Y. The value of g on Y is 8.1 m/s².
(a) What is the ratio of the mean density of X to that of Y (Px / Py)?
(b) What is the value of g on X?
m/s²
(c) The mass of Y is 4.372 x 1024 kg. What is the escape speed on X?
m/s
