Homework Help: Motion with Constant Acceleration

  1. Oct 30, 2009 #1
    1. The problem
    A motorcyclist slows down uniformly as he approaches a red light. He takes 3.2 seconds to come to a halt and travels 40m in this time.
    How fast was he travelling initially?

    2. Relevant equations

    Any other kinematic equations? If you can find his acceleration, I bet you could find his initial velocity.
