Circular motion of a boat

  1. Apr 8, 2009 #1
    1. The problem statement, all variables and given/known data
    A boat is traveling along a circular path having a radius of 20m. Determine the magnitude of the boat's acceleration when the speed is v=5m/s and the rate of increase in the speed is v'=2 m/s^2

    2. Relevant equations

    a=(a(t)^2+a(n)^2)^1/2

    3. The attempt at a solution

    I believe the a(t)=2 <--- May be wrong
    and the equation for a(n)=v^2 / p which i got 1.25
    so i pluged these into the relevant equation to get 2.36 m/s^2 is the magnitude of the boats acceleration

    my question is if i did it right or not
