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 37000 km/h. The original speed of the comet at that time was about 40000 km/h, and its mass was estimated to be in the range (0.10?2.5)×1014kg. Use the smallest value of the estimated mass.
Part A What change in the comet's velocity did this collision produce?
Part B Would this change be noticeable?
Would this change be noticeable?
Part C Suppose this comet were to hit the earth at 40000 km/h and fuse with it. By how much would it change our planet's velocity? (The mass of the earth is 5.97×1024kg)
