A 10kg box at rest is being pushed on a frictionless surface by a force of 10N. The force is in the same direction as the motion of the box. 10 seconds later, how much kinetic energy will this box have?

2. Relevant equations

1. F=ma

2. V_{f}=V_{i}+at

3. E_{k}=0.5mv^{2}

3. The attempt at a solution

I used formula 1 along with the F and mass to find the acceleration to be 1 m/s^{2}. Then, I plugged that into formula 2, given an initial velocity of 0, acceleration of 1 m/s^{2}, and a time of 10s. This gave me V_{f}at 10m/s. I used that in formula 3, with mass being 10kg. This gave me a final E_{k}of500J.

Is this correct? 500J seems a little high but, I've no clue how else to do this. Thanks in advance.
