   1. The problem statement, all variables and given/known data
   
   The altitude of the space shuttle during the first 30 s of its ascent is described by the expression у = bt², where the constant b has the value 2.9 m/s². Using calculus, obtain an expression for the velocity and acceleration of the space shuttle during this period.
   
   
   3. The attempt at a solution
   
   y' = 2bt
   y'' = 2b
   
   Book is giving me the following for answers:
   y' = bt
   y'' = b
   
   Am I doing something wrong?

   No, your answers are OK, as long as you are sure which is velocity and which is acceleration. I have no idea what the book was thinking by giving those answers.
