8. A comet with unknown mass mc is in an elliptical orbit around the sun: R. Rp mc mc MS ū When the comet is at its parahelion R, it has a speed of up = 80km/s and at its aphelion R, it has a speed of va = 10km/s. For this problem suppose we do not know the mass of the sun M, or the value of Newton's constant G, but we can approximate the orbit of the earth...

Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0 km and a mass of 2.5×1014 kg hits the earth with an impact speed of 3.0×104 m/s . What is the earth's recoil speed after such a collision? Assume that the mass of the...

Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0 km and a mass of 2.5*10^14 kg hits the earth with an impact speed of 4.0*10^4 m/s. Part A: What is the earth's recoil speed after such a collision?

Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 22.424 kilometers. The neutron star has mass...

A dwarf planet with mass M = 2.43 x 1016 kg and radius R = 2360 km is crashed into by a large comet. The dwarf planet initially has a day with length 12 hours. The comet hits the planet at its equator and at an angle of 0 = 80° with the radius of the planet, as shown in the view of the planet looking above from the North Pole. The speed of the comet is V comet =...

A 507 kg satellite is in a circular orbit at an altitude of 754 km above a planet’s surface. This planet is similar to our Earth. Because of air friction, the satellite eventually is brought to the Earth’s surface, and it hits the Earth with a speed of 3 km/s. The radius of the planet is 7 × 106 m and its mass is 8 × 1024 kg. The gravitational constant is 6.67259 × 10−11 N m2 /kg2. How much...

Exercise 3.28 The radius of the earth's orbit around the sun (assumed to be circular) is 1.50 x 10° km, and the earth travels around this orbit in 365 days. Part A What is the magnitude of the orbital velocity of the earth in m/s? - Part B What is the radial acceleration of the earth toward the sun? Part What is the magnitude of the orbital velocity of the planet Mercury radius 5.79 x 10 km orbital period =...

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...
