Deep Impact Mission. In July 2005, NASA’s “Deep Impact” mission crashed a 372-kg probe directly onto the surface of the comet Tempel 1, hitting the surface at 37,000 km/h. The original speed of the comet at that time was about 40,000 km/h, and its mass was estimated to be in the range (0.10 – 2.5) × 10 14 kg. Use the smallest value of the estimated mass, (a) What change in the comet’s velocity did this collision produce? Would this change be noticeable? (b) Suppose this comet were to hit the earth and fuse with it. By how much would it change our planet’s velocity? Would this change be noticeable? (The mass of the earth is 5.97 × 10 24 kg.)

Calculate the location of the center of mass of the earth-moon system (that is, find the distance of the center of mass from the earth's center). The mass of the earth is mE=5.97×1024kgmE=5.97×1024kg and the mass of the moon is mM=7.35×1022kgmM=7.35×1022kg. The distance between the earth and the moon is d=3.84×108md=3.84×108m. Assume the orbital radius of the moon is equal to the distance between the centers of the earth and the moon.
Express your answer with the appropriate units.
Where is the center of mass with respect to the earth's surface? Assume the radius of the earth is 6.38×106m6.38×106m.
Express your answer with the appropriate units. Enter positive value if the center of mass is above the earth's surface and negative value if it is below.
Pluto and its satellite Charon have masses which are more similar to each other than any other knonw pair of orbiting bodies in the Solar system. How far from the center of pluto is the barycenter or center of mass of the Pluto-Charon system? Take the mass of Pluto to be 1.31 × 10^22 kg, and 1.59 × 10^21 kg for Charon (about one eighth that of Pluto). Assume Pluto and its moon Charon are separated by 19,640 km while the radius of Pluto and Charon are 1190 km and that of Charon are 606 km respectively. Treating Pluto and Charon as spherically symmetric objects, how far from Pluto is the barycenter of the Pluto - Charon pair, and is this point inside are outside of Pluto?
Hint: Place Pluto at the origin and Charon on the x axis.
A. 289 km; inside
B. 781 km; inside
C. 2130 km; outside
D. 5910 km; outside
To mend satellites approaching one another at a relative speed of 0.350M/S intend to dock. The first has a mass of 5.50×10^3 kg , and the second a mass of 7.50×10^3 kg . If the two satellites collide elastically rather than dock, what is their final relative velocity? Adopt the reference frame in which the second satellite is initially at rest and assume that the positive direction is directed from the second satellite towards the first satellite.
