(adsbygoogle = window.adsbygoogle || []).push({}); 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.
