## Homework Statement

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?

## Homework Equations

1. F=ma

2. V

_{f}=V

_{i}+at

3. E

_{k}=0.5mv

^{2}

## 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}of

**500J**.

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