Homework Help: Can you solve this?

  1. Jun 5, 2008 #1
    How do you solve this problem?

    An object of mass 0.5 kg is thrown straight upward with an initial speed of 8 m/s. Its total flight time - from release to impact - is 3s. From what height was the object thrown? (Ignore effects due to the air.)

    I am not a physics student. I am a virologist who is trying to learn general physics for tutoring purposes. Just thought this would be a good place to post. Thanks!

    Yes I can solve it but this sounds like homework so what have you tried so far?
