In 1993 the spacecraft Galileo sent home an image of
asteroid 243 Ida and a tiny orbiting moon, now known as Dactyl.
This was the first example of an asteroid-moon system. The
moon is only about 1.5 km wide and Ida is about 55 km long. The
orbit of Dactyl is not well known, however it can be used to make
an estimate of Ida’s mass. (a) If we assume that
Dactyl’s orbit is circular, with a radius of 87...

In 1993 the spacecraft Galileo sent home an image of asteroid 243 Ida and an orbiting tiny moon (now known as Dactyl), the first confirmed example of an asteroid moon system. Other such systems have since been discovered. Assume an asteroid's moon is 1.6 km wide, and that its center is 116 km from the center of the asteroid, which is 55 km long. The moon's orbit is circular with a period of 24 h. (a) What is the mass...

Assume that the density of an average asteroid is 3.1 kg/L, and that the craters on the Moon are roughly 15 times the size of the impacting body. a. What was the diameter of the asteroid that created the 240-km-diameter Clavius crater? D= 16 km Using the density of an average asteroid, calculate the mass of this asteroid. m= *10 15 kg b. Calculate the kinetic energy of this impact if the speed of the asteroid was 22 km/sec relative...

The crew of a stationary spacecraft observe an asteroid whose mass is 4.00 x 1017 kg. Taking the location of the spacecraft as the origin, the asteroid is observed to be at location < 7.00 x 103, -3.00 x 103, 10.00 x 103> m at a time 18.2 s after launch time. At a time 19.2 s after launch time, the asteroid is observed to be at location < -2.10 x 103, 0.90 x 103, -5.00 x 103> m. Assuming...

On February 7, 1999, NASA
launched a spacecraft with the ambitious mission of making a close
encounter with a comet, collecting samples from its tail, and
returning the samples to Earth for analysis. This spacecraft,
appropriately named Stardust, took almost five years to
rendezvous with its objective-comet Wild 2 (pronounced "Vilt
2")-and another two years to return its samples. The reason for the
long round trip is that the spacecraft had to make three orbits
around the Sun, and also...

A spacecraft of mass m = 1900 kg is moving on a circular orbit about the earth at a constant speed v = 5.12 km/s. [Given: Mass of the earth M = 5.98 times 10^24 kg, radius of the earth R = 6.37 times10^6 m, gravitational constant G = 6.67 times 10^-11 N.m^2/kg^2.] a. Determine the radius r of the circular orbit. b. What is the period T of the orbit? c. The satellite, by firing its engines, moves to...

Problem 3: The Rosetta spacecraft landed a probe on the comet Churyumov-Gerasimenko. It has a mass of appeoximately 1 x 10 kg and has an average density of approximately 400 kg/m. It is far from spherical, but for this problem go ahead and assume it is spherical. Estimate the radius, the acceleration due to gravity at the surface and the escape velocity from its surface.

Analysis Model Tutorial A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 3,125 kg. It has strayed too close to a black hole having a mass 125 times that of the Sun (see the figure below). The nose of the spacecraft points toward the black hole, and the distance between the nose and the center of the black hole is 10.0 km Black hole 100 m 10.0 km...

1. [12 points] Compelling evidence for the asteroid impact 65 million years ago which triggered the extinction of the dinosaurs was discovery of a thin Iridium-rich clay layer in sediments all around the world. A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...
