Moving particle acceleration problem

  1. Jan 29, 2008 #1
    1. The problem statement, all variables and given/known data

    At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of vi = (3.00 i - 2.00 j) m/s and is at the origin. At t = 2.50 s, the particle's velocity is v = (6.10 i + 4.90 j) m/s.

    (a) Find the acceleration of the particle at any time t. (Use t, i, and j as necessary.)

    2. Relevant equations

    avg. acceleration = change in Velocity / Change in time

    3. The attempt at a solution

    I subtracted the two vectors (vf -vi) and this is what I got for my equation to find acceleration of the particle at any time t.

    avg accel. = (3.10i+6.90j)/t

    but when I entered this into the web page I got the answer wrong. Any suggestion would be appreciated.

    constant acceleration means a fixed number. so it will not be in term of t. simply divide by 2.5 s to get the number.

    right?
