In July 2005, NASA's "Deep Impact" mission crashed a 372-Rg pro the surface of the comet Temple 1, hitting the surface at 37000 km/h relative to the comet. The original speed of the comet at that time was about 40000 km/h, and ite mass was estimated to be in the range (0.1 – 2.5) x10“ 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 earth and fuse with it, by how much would it change our planet's velocity? Would this change be noticeable? (mearth = 5.97 x1024 kg)

Question

Give me the solution for the problem.

The correct answers are:

A: -1.4 x 10-6 km/h. The comet's speed has been decreased by this amount. Hence, the effect is negligble.

 

B: -6.7 x 10-8 km/h. The Earth's speed has been decreased by this amount. Also, the effect is negligble.

In July 2005, NASA's “Deep Impact" mission crashed a 372-kg probe directly onto the surface of the comet Temple 1, hitting the surface at 37000 km/h relative to the comet. The original speed of the comet at that time was about 40000 km/h, and its mass was estimated to be in the range (0.1 – 2.5) x10“ kg. Use the smallest value of the estimated mass. A.
