Find the speed of the particle after 0.2 seconds

  1. Oct 30, 2016 #1
    1. The problem statement, all variables and given/known data
    The particle is thrown horizontally with speed 10 m/S (I believe from a height). Find the speed of it after 0.2 seconds.

    2. Relevant equations

    3. The attempt at a solution
    v=sqrt(100+4)=10.198m/S Am i right?

    Looks right to me. I think it is probably more common to use 9.8 ms-2 for gravity though.
