    Incorrect Textbook Answer involving kinematics?

    HAHA yes you are correct. Thanks! The direction a decimal moves when converting something as simple as meters to km can make or break you!

    Incorrect Textbook Answer involving kinematics?

    There it is! Glad to see I'm not crazy, just careless with the direction a decimal should move sometimes :)

    Incorrect Textbook Answer involving kinematics?

    vf=0 km/hr vi = 100 km/hr x = 80,000 km vf2 = vi2+2ax 0 = 100^2 + 2a(80,000) 160,000a = -10000 a = -0.0625 km/hr^2 This is off by 1,000,000 times from the textbook answer. Am I missing something with units or something or is the book wrong?
