Question

Use the information in the following table, as necessary, to answer the following questions: You will need more than the information in the table, but, use the table if you have the need for any data in the table. What is the density of Mars? (in kg/m3) What is the gravitational constant (G) on Venus? If something weighs 100 pounds on Earth, what would it weigh on Venus? What would the mass be of an object that was 100 kg on Earth, if you measured it on Venus? What is pi on Mercury, to 5 decimal places? What is e on Mars, to 5 decimal places? If a Martian scientist dropped a 10 kg mass and a 25 kg mass from the top o leaning building on Mars, neglecting air resistance, which mass would hit the ground first? How long would it take for an object to hit the ground, if it were dropped from a height of 150 feet on Earth? Use x=1/2 a t2 We add a new planet to our solar system (to replace Pluto). It is spherical, with a mass of 2.99 Times 1024 kg (half of Earth's). The acceleration due to gravity, near the surface of the new planet is 9.8 m/s2.[Same as Earth] What is its radius in kilometers?

Explanation / Answer

Density of Mars = m/V = 6.42*10^23/ (4/3*pi*r^3) =3.9*10^3 kg/m^3 Gravitation constant in Venus = mu/M = 324,859*10^9/4.87*10^24 = 6.67*10^-11 m3 kg-1 s-2 The gravity on Venus is about 9/10 that of Earth. So, a 100 pound object on Venus would weigh W=mg therefore it weighs 90 pounds in Venus. Mass of an object in any planet is same. Pi will be same in any planet e will also be same in any planet
