Homework Help: Is it possible to have a positive acceleration and slow down?

  1. Oct 9, 2007 #1
    (1) Is it possible to have a positive acceleration and slow down?
    (2) Is it possible to have a negative acceleration and speed up?

    I believe both answers are yes, but I need someone to clarify how.
    Please help.
    Thanks

    You are indeed correct. Think about what type of quantity acceleration is, compared to speed.
